$A$ population will not exist in Hardy-Weinberg equilibrium if

If the frequency of the '$A$' allele is $0.4$,find the frequency of the '$B$' allele and the heterozygous genotype in a random mating population at equilibrium.

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 $\%$)?

Hardy-Weinberg equilibrium is affected by -

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?

Enumerate three most characteristic criteria for designating a Mendelian population.
