Regarding the genetic structure of the population, the following two hypotheses have been proposed:- 1. Classical Hypothesis 2. Balance Hypothesis. Model # 1. Classical Hypothesis: It was developed by T.H. Morgan (1932) and supported by H.J. Muller and Kaplan (1966). The classical hypothesis proposes that the gene pool of a population consists at each gene locus of a wild-type allele [...]
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 [...]
