There are two alleles, b and b, at a gene locus in a population at hardy-weinberg equilibrium. the relative frequency of the dominant (b) allele is 0.7. what is the expected number of heterozygous individuals if the total population size is 500 individuals?

210

Explanation:

Frequency of dominant allele is represented by "p"

and frequency of recessive allele is represented by "q"

Given

Thus,

As per Hardy Weinberg's second equation of equilibrium -

Substituting the given values in above equation, we get -

So the total number of heterozygous individual is equal to

poor water quality affects most estuarine organisms, including commercially important fish and shellfish. the pollutants that have the greatest impact on the health of estuaries include toxic substances like chemicals and heavy metals, nutrient pollution (or eutrophication), and pathogens such as bacteria or viruses.
