State and explain any three factors affecting allele frequency in populations.
What is founder effect ?
According to Hardy-Weinberg principle, allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences. It makes several assumptions which were given below.
$i.$ Random Mating
$ii.$ Sexual Reproduction
$iii.$ Non-overlapping Generations
$iv.$ Occurrence of Natural Selection
$v.$ Small size of population
Identify two assumptions which do not meet for a population to reach Hardy-Weinberg Equilibrium?
Organic evolution would have not been taken place
Gene pool is referred to
