Manja Posted November 13, 2019 Share Posted November 13, 2019 Definition Genes are the smallest unit of genetic material. Genes are present in each locus that is unique to the chromosomes. Genes are the smallest genetic substances consisting of fragments of DNA that determine individual traits through the formation of polypeptides. So, genes play an important role in controlling the traits of individual heredity. The genes in the chromosome have no clear boundaries. Nevertheless, genes can be compared in a sequence and orderly to the chromosome thread. In body cells, chromosomes are usually paired. A pair of chromosomes are homologous to each other, meaning that they have the same shape and locus of corresponding genes. The genes found in these corresponding loci are called alleles. function Genes are a chemical entity. As a material for heredity, genes have several functions, including: a) As a separate particle on the chromosomes. Zarah is the smallest substance and cannot be divided anymore. b) Conveying genetic information from the parent to the offspring. c) Regulate metabolic processes and development. Alleles can have the same or opposite tasks for a particular job. Alleles that have the same task are called homozygous alleles. Meanwhile, alleles with different tasks are called heterozygous alleles. Alleles that have the same task, for example the black color determining gene in wheat which has a black color determining gene pair as well. Examples of alleles whose task is opposite are the black color-determining gene in wheat having a pair of white color-determining genes. -1 Link to comment Share on other sites More sharing options...
