Genetics

Ive had many a debate with friends about athletic abilty being inherited and not learned, or gained through practice. Is there a gene, or group of genes that can be passed on by parents that will make a child be more predesposed to have raw athletic ability? My friend argued that had I grown up with him and participated in the same sports activities that he did, That I would be just as athletic as he. I argued NO, I wouldnt be. Yes I would be more athletic than I am now, But not near the atlete he was and is. I say that some folks have more of a tendancy to exibit athletic prowess than others, Due to inherited genes. Only with athletic activity does one hone those skills …

Everyone likes to think that if your mother's father is old and has all his hair, then you will have yours when you're old. Likewise, if he loses it, then you will lose yours too. I have a feeling this isn't true and that it really all has to do with genes. Do you guys know anything about this, or any other way I can tell if my hair will fall out?

Since blonde hair and blue eyes result from 2 recessive genes, Is it correct to assume that a blonde hair/blue eyed mother and father can only produce blonde hair/blue eyed children? Since they both have 2 recessive genes to offer for each trait , Wouldnt all of their offspring all have the 2 recessive genes, Thereby all being blonde hair and blue eyed?

Can anyone provide me an internet source of any recent science journal articles that relate to tools or techniques used for DNA or RNA? I'm not sure where to start looking, most links I got in google are just specific texts from a university's lecture... please give me some suggestions, thanks a lot!

Hey y'all. I hafta do a science fair project for my Bio class so I'm trying to find a link between hair and eye color. PLEASE READ: THIS SURVEY IS FOR CAUCASIANS(which i'm defining as being of EUROPEAN DESCENT)ONLY!! not being racist or anything like that, this is just the easiest way to do it and get reliable results. PLEASE PLEASE PLEASE BE HONEST!! It's realllly important. To everyone who fills this out: THANKS, I LOVE YA!! 1. Age? 2. Gender? 3. Where do you live? 4. Natural hair color? 5. Natural eye color? 6. Do you dye your hair(what color)? Or what do you want your hair color to be?(you don't have to pick a different color) 7…

well iam reading this paper for some evolution class, and its about two drosophila youngsters with similar sequences for Adh gene....that bit donesnt really matter all i want to know is whats going on with these transposons....it seem that finally a transposed sequences has developed a function and not just messed everything up....this was decided upon by having a increased number of slient mutations, and no new stop codons....thus positive selecting for this sequence....well anyway why is this so uncommon to have transposition with function, i understand that it would also be a new function by stealing parts of an orginal sequence.... or at least the first part, because …

This is sort of stupid questions that I learned this before but I can't remember now. What is exactly difference between the mitosis and meiosis? I know that the mitosis is the division of the two nuclei but when I got to the part of the chromatin, I got lost. What is the DNA double helix and how this differ from chromosome itself? Also, from the cell cycle, I see the word interphase. There are three part, G_1, S, and G_2. What is the difference between each step? Appreciated greatly. Happy New Year!

Just read the news on the Parkinson's Gene - they have found a mutation on a gene in about 5-8% of Parkinsons patients. Can anyone tell me why this is statistically (or otherwise) significant? from http://www.healthtalk.ca/parkinsons_gene_011805_37982.php also at: http://www.reuters.co.uk/newsArticle.jhtml?type=healthNews&storyID=7348093 Thanks, J

This was a problem from my school. I think I'm pretty sure that I'm right but I just want to be sure. Say there's this guy named Bob with hemophilia. He marries with a woman named Cathy and they have six children, three of them are daughters and three of them are sons. None of them has hemophilia. The daughters, in order from their age, are Jessica, Ellie, and Lauren. Jessica marries with a guy and have two sons with hemophilia and two daughters with no hemophilia. Ellie also marries with a guy and have one son who is also hemophilia. Lauren marries with a guy and among their four children, she has one son with hemophilia and three daughters who are healthy. Bob and C…

According to what I read, the sickle cell anemia is caused by substitution of one nucleotide and it is common on Africa and Asia, especially to African people because of resistance to malaria. I'm not sure I understood what that means. I'll add the quote from the book. Also, does this relate to the person's bloodtype also? Maybe this isn't too smart question but does the Landsteiner's bloodtype (which is just another name for common bloodtypes, A,B, AB, and O), influence to the person's bloodtype? Thanks for the replies. Happy Holidays

I read that dna is wound to a specific degree and then as we get older that it unwinds and that that contributes to aging. Is that true?

I read that cancer cells have their dna wound back wards. Is that true? I doubt it, but maybe somebody can shed some light on that.

Ok. The two things as titles are confusing me. Both are the traits, right? And both were also influenced by genes. But I don't understand what is their major difference. Like colorblindness is an example of sex-linked while baldness is sex-influenced.

Does anyone know where I could download a good Gel Electrophoresis animation, that covers only basic information. Thanks in advance!

Does anyone know where I can get a copy of Watson and Crick's original research paper, preferably online?

A few years back, when my grandmother was still alive, she and her three daughters went to the local health fair. At the fair they were able to get their blood pressure checked and be screened for diabetes. One test they availed themselves of was a blood typing test. It turned out that my mother and my grandmother shared the same blood type, B. My two aunts were O and A repectively. My grandfather has been long dead and there is no possibility of now knowing his blood type. My mother always wondered if the outcome of this test meant that one of her sisters was not a true biological sister. (There were rumors that the middle sister was adopted.) I know nothin…

okay, in replication one strand is replicated continuously and the other is discontinuous due to nucleotides can only be attached in one direction, so one side has to constantly start and stop (i know this has a specific term related to it) does this make the discontinuosly replicated strand more error prone because the polymerase has to constantly re orient itself?

I have few questions for the genetics. This thread can be posted on the general biology forum but especially this part is genetics, so I'm putting here I just hope it's not too easy concept if this forum only talks about complicate genetics Question that I didn't understand. You plant 50 yellow peas which were grown on a tall plant. When the plants mature, 28 are tall with yellow seeds; 8 are tall with green seeds. How mnay plants would you expect to be short with yellow seeds and how many would be short plants with green seeds? [math]\text{Only thing I just assumed was that the genotype of the parent} [/math] [math]\text {Which would be TtYy. The reason i…

Let me put it another way: Do dominant genes ultimately lead to a phenotype that has the greatest chances of survival, or are these completely unrelated? Could a couple have 3 out of 4 children who are "weaker" than the fourth child? Gib

Hey can anyone provide links for Canadian statistics on Turner's disease.Have to do a project includin canadian statistics, genetic mechanism or cause, symptoms and treatments. But all pics no words. Ne ideas how i should approach this predicament o btw it has to be hand drawn Thanks in advance

A looming avian influenza pandemic is looming large threatening 1/4 of the world's population http://www.recombinomics.com/pandemic_potential.html However, most of the scientific effort has focused on gene re-assortment, while the true driver is recombination http://www.recombinomics.com/viral_evolution.html The virus continues to mix and match and stays a step ahead of vaccine development http://www.recombinomics.com/H5N1_H9N2.html This year may be the last shot to catch up, but Chiron can't even get a known vaccine out the door. Looks like there will be some serious challenges ahead. Comments?

There has been considerable debate as to whether there is recombination in Human Mitochondrial DNA over the past few years. Are there evidences supporting this fact? How does it occur? What are the causes?

skin color as i know is a genetic trait.so our color is predetermined by our parents. but then can we change it during our life time? how true are the cosmetic gizmos that say its posssible. another thing....children as ive seen(some) are fair in childhood but after turing around 15-20 they express darker complections.how can this be explained?

I just read an article in Scientific American that challenges the central dogma for eukaroytic cells. To sum it up, instead of the introns going to waste, some of it become micro RNAs that allows extremely complex organisms like us to exist. This would also explain eukaroytic cells have introns because they are beneficial and thus would survive under natural selection. However, prokaryotes do not have a nucleus necessary to perform the splicing needed by introns. Any thoughts?

Im working on a project about GM foods and if anyone has anything intresting they want to share it would be much appreciated
