In a population that is in Hardy Weinberg equilibrium, the frequency of a recessive allele for a certain hereditary trait is 0.20. What percentage of the individual in the next generation would be expected to show the dominant trait?
Text Solution

As the population is in Hardy Weinberg equilibrium, the frequencies of alleles will remain the same for the next generation also. According to the question, the frequency of recessive allele is
. Frequency of dominant allele,
. Hardy Weinberg law states that the sum of all genotype frequencies is represented as the binomial expansion of the square of the sum of
and
. This sum is equal to one.
. Hence, the frequency of homozygous dominant genotypes in the total population
or
. And the frequency of heterozygous dominant genotype in total population
or
. The frequency of dominant individuals in next population
96%.
