Gene Pool and Gene Frequencies
Gene pool and gene frequencies are considered to be two important attributes of a population. A gene pool
is the sum total of genes in reproductive gametes of a population. The gene pool is transferred from one generation to the other through the sample drawn from a gametic pool. This sample of gametes will form zygotes of next generation so that the gene pool of next generation will depend upon the kind of random samples drawn to form zygotes. Gene pool of a population will consist of a large number of genes which will vary in their frequencies. Gene frequencies
are defined as proportions of different alleles of a gene in a population, and in a particular generation these frequencies will depend upon their frequencies in preceding generation. These frequencies also depend on proportion of various genotypes in total population. For instance, in human MN blood groups (Multiple Alleles (Based on Classical Concept of Allelomorphism)
), if we sample a population of 100 individuals with 50MM,
, frequencies of 'M'
can be calculated.
