Chance Mating in Mendelian Population | Genetics

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 [...]

Calculating Gene (Allele) Frequencies in a Population | Genetics

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 [...]

Major Histocompatibility Complexes and Its Classes | Genetics

In this article we will discuss about the major histocompatibility in human body and its classes. B and T cells contain membrane receptors that react with specific antigenic determinants. B cells are activated by interaction with the antigen either in its dissolved form or while it is still a part of the surface of the pathogen. In contrast, the T [...]
