In which of the following conditions does the gene frequency remain constant in a population?

Name the law that states that the sum of allelic frequencies in a population remains constant. What are the five factors that influence these values?

$A$ gene locus has two alleles $A$ and $a$. If the frequency of the dominant allele $A$ is $0.4$,then what will be the frequency of homozygous dominant,heterozygous,and homozygous recessive individuals in the population?

Explain the Hardy-Weinberg principle using an algebraic equation.

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

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