The eyes of insects and the eyes of vertebrates were, until the early 1990s, considered to be a standard example of "analogous" structures. They perform the same function but have utterly different internal structures, suggesting that they evolved independently from a common ancestor that lacked eyes. Then the laboratory of Walter Gehring in Switzerland began to research genes that are [...]
Just as the gene frequency is controlled in the genetic laboratory, so is the mating pattern, generation after generation. But outside the laboratory, chance mating is a chance or random affair. Every member of Mendelian population, thus, depends on chance or random matings. In other words, every male gamete in the gene pool has an equal opportunity of uniting with [...]
Application of Hardy-Weinberg law in calculating Gene (Allele) frequencies in a population. The gene frequencies for the autosomal and sex-chromosomal allele can be determined by the help of Hardy-Weinberg law by the following method: A. Calculation of Gene Frequencies of Autosomal Genes: An autosomal gene locus may have codominant alleles, dominant and recessive alleles or multiple alleles. If one desires [...]
