In a population exhibiting random mating,the frequency of a disease-causing recessive allele is $80\%$. What will be the frequency of carrier individuals in the population (in $\%$)?

Enumerate three most characteristic criteria for designating a Mendelian population.

According to the 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 are 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 the criteria for a population to reach Hardy-Weinberg Equilibrium.

In a population at Hardy-Weinberg equilibrium,the frequency of allele '$A$' is $0.6$ and the frequency of allele '$a$' is $0.4$. What will be the frequency of heterozygotes in the population?

In the Hardy-Weinberg equation $p^{2} + 2pq + q^{2} = 1$,which term represents the frequency of the homozygous recessive genotype?

If $51\%$ of the members in a population possess at least one recessive allele,find the frequency of the dominant phenotype.
