Genetics

Is there a research for new learned knowledge transferred by an organism for generations. Thanks

hello i am beginner in Bioinformatics ,as i have gone through post of all members posted about branch length. as i am working on gene name msp ,i m not getting how to interpret the result i have used Bayes software , and calculated branchlength with bayesian posterior distrubution. plz fined attached files Hope somebody help me out in this matter , all gens are of same organism . i need to fine variation in terms of branch length

So roughly how long have we known about it? Pondered on its existence and confirmed? I guess science has been well aware for over 100 years and in the past 60 we have been making leaps and bounds. - http://www.buzzle.com/articles/who-discovered-dna.html I'm just wondering, how much do some of you think we know? Are we still making finds or is it pretty well figured out?

Why they don't do more Genome wide associations studies on homosexuality to find the affected genes???

Hi there, I want to discuss a bit of a dark topic - biowarfare. As you are likely to be aware, genes can sometimes have polymorphisms. i.e. A different form of the gene due to the substitution of a different amino acid at a certain position on the gene. In some cases, certain ethnic groups are more likely to have a higher frequency of one polymorph than another, such that the population skews toward one polymorph. For example, the enzyme paraoxonase is responsible for hydrolysing the metabolite oxons of toxic organophosphate compounds such as chlorpyrifos oxon and diazoxon. One of the major polymorphs of this gene is the Q192R alloform, where either a glutamine…

Let's say a 20 year old man named Peter, has below normal health due to his smoking habit and a lifestyle of poor nutritional diet. He has a child with his wife and a daughter is born. During the next 5 years, Peter changes his lifestyle drastically. He quits smoking and improves his diet. Further, he also embarks on a regimented exercise program and builds an impressive physique. He becomes an athlete. At age 25, he has another daughter. Considering all other things constant (wife has no changes in her lifestyle and neither has the first born), will the second daughter possess superior genes? Thank you for your insight. AMT-

Hi, need some help, this is driving me crazy, this is not an assignment just review question that i cant get my head around, just need to be pointed in the right directions Two doubled-haploid (homozygous) lines of canola differ in leaflength. In one, the average leaf lengthis 30 cm, and in the other it is 15 cm. In both lines, the variance in leaf length is 2 cm2 whengrown in similar environments. In the F2generation of a cross between these lines, the average leaf length is 22.5 cm,with a variance of 5 cm2. (Hint: DO NOT ASSUME THAT THE ENVIRONMENTAL VARIANCE =0) a. What is the genotypicvariance? so from the lecture notes, it doesnt cover much but …

I often come across statements similar to the two below, which make sense in isolation but contradict each other when seen together: 1. We share 50% of our genes with a full sibling. 2. We share 90% of our genes with mice (or similar numbers for other species). There's obviously some distinction in definition not being revealed here - could someone explain it to me?

Hello! I am not genetician, but more biochemist/cellular biologist. Therefore, my question is if it is possible and if yes, then HOW it is possible to create a cell line with knochout of only one allele of gene? I understand general principles of generating of full knockout. Don't jugde if the queastion is too naive. I am grateful for an answer or a reference to source of wisdom.

Hallo eveyrone In male cells, the chromosomes x y are separated in anaphase so how in the daughter cell there is the same genetic data as in the mother cell? one cell got a x chromosome the the other y.. What did I miss?

I have light brown hair with occasional blond hairs in it. My mom has brown hair and a blonde brother and sister My dad has black hair and a blonde mother What are my chances of carrying the blonde gene?

Many books have been written about the identity of the infamous Whitechapel Murderer of 1888, better known as Jack the Ripper. There are presently about 200 people seriously suspected of having committed the crimes, and their relatives could in many cases still today be traced through historical records. While little crime scene evidence from the murders has been preserved, one anonymous letter written to the police at the time of the murders has been held by many scholars of these crimes to be an authentic letter from the true killer. This letter has a stamp affixed to its envelope, and the glue on the back of that stamp had to be licked -- presumably by the killer --…

Hi, I'm developing a web site about bioinformatics, linking new papers and tools for data analysis, but also with more general topics concerning genetics or science. The url is: http://bioinfospace.altervista.org/ Thank you I.

I've not studied genetics formally but considering it after reading some pop science and browsing research. I came across this paper recently and it's interesting, could anyone comment who has more experience in this area? http://www.nature.com/mp/journal/v14/n8/full/mp200944a.html

Since this is my first post I send my "hi" to everyone . I have few questions to topic mentioned in title: 1.Is there one gene responsible for breast size and shape, another for legs and thighs... or the overall silhouette depands on one gene? 2a.And in case of breast (or silhouette) - which shapes(and sizes) are recesive and dominant? 2b.What are the combination of allels? 3.How big influence on inheriting these traits have father's chromosomes (X,Y)? I've heard from my friends that most of them inherited breast size (I mean they are similar in shape) after mother or grandmother (from mother line; mine is quite similar to my mother). My mother …

Racial intelligence is like any other human trait, which is a complex interaction between a person's genetic makeup AND the environment in which a person is socialized. Consequently, those who argue that racial intelligence has no biological component are extremely likely to be mistaken. Although psychometric testing is neither a reliable nor accurate measure of intelligence, it doesn't imply that we cannot, and should not look to other sources as a barometer and indicator of racial intelligence. For instance, Africa has no historical or indigenous civilization to boast, except for the civilizing influence of the Arabs, Persians, and Europeans; as indeed, withou…

I am producing a genetics educational game with an emphases being a fun game and having accurate science. It will be a a free online game based on breeding animals. I was wondering if you could tell me what do you wish people already knew when you first talk to them about genetics to them? For example -XY sex linked genes -dominant/recessive genes -terminology such as homozygous, heterozygous. -that some non obvious traits such as eye defects and coat color are related. -linkage distance between genes. -some thing else completely different. I am looking for which points I should emphasize in the game. I have put a facebook page, a feedback page to t…

Howdy, I am looking to determine the (geographic) race of my great-grandfather. He unfortunately hid his past because of political pressure at the time and I only know he is east Asian. Unfortunately all I have to go on is a couple pictures. Now that its no longer a taboo subject my family would be immensely grateful if anyone with the expertise would be willing to give it a shot. My first guess would be Chinese but I'm no expert. I'd be happy to PM a picture. I apologize if this is the wrong place. Thanks

How does genetics play a role in when you start puberty and what your final height will be? My mom (5'7) and my dad (6'3) were both VERY late bloomers. I however, am 6'2 at 14 years old and I have no idea how I am... Any ideas?

Is the synthetic dna which is manmade, made organic just like the original dna? Thanks.

Hi all, I would much appreciate if somebody could point me in the right direction to working out a few simple things about a child based on it's parents and maybe grand parents features. I would like to start with something simple like hair or eye colour, height or whatever is easiest (hair would be best if possible). So if someone could explain how to work it out and back it with some links to formulas that can be understood by a regular person that would be great! The scenario would be, e.g: man with blond hair + woman with dark hair = what is the most probable hair colour for their child and what is the probability. Then to narrow it down (complicate i…

! Moderator Note Thomas I have moved the OP in this thread to your already existing thread on Racial intelligence is a function of nature and nuture. Please keep the discussion of this topic in the single original thread and do not open any more on this subject.

Controlling for social, cultural, and economic factors in deciding the outcome of elections, Hamiton's rule in regards to genetic altruism can be used to predict whether or not a candidate for office is likely to succeed: rB > C Kin selection Consequently, there are some who argue that Barack Obama's historic election by White voters on November 4, 2008 was partly due to the fact that he is partly of European stock. Contrast the example of Obama with Jesse Jackson and other black candidates who have never made it to the top, and we therefore have a compelling case to argue that Obama's landslide was partly as a result of his Mixed-Race heritage, and his popular ap…

Mitochondrial DNA is inherited maternally and codes for around 13-14 proteins. However, the majority of proteins associated with the mitochondria are encoded by genes contained within nuclear DNA, which is inherited from both parents. Excluding aberrant mutations in either genome, do conflicts sometime arise due to this dynamic? Can the maternally-inherited mtDNA sometimes be incompatible with the mutually-inherited nuclear DNA? If so, would the fertilized ovum abort immediately, or could issues arise later on in life?
