First answer is correct. Eutrophication can have serious effects, like algal blooms that block light from getting into the water and harm the plants and animals that need it. If there's enough overgrowth of algae, it can prevent oxygen from getting into the water, making it hypoxic and creating a dead zone where no organisms can survive.

sineoko [7]

Answer:

$0.547$

Explanation:

Given -

Total Population - $500$

Individuals with homozygous HbA/hbA genotype - $150$

Individuals with homozygous hbs/hbs genotype - $150$

Individuals with heterozygous hba/hbs genotype - $200$

Let us assume the given population is in Hardy Weinberg' equilibrium

The frequency of individuals in the given population with homozygous HbA/hba genotype is equal to number of individuals with homozygous HbA/hba genotype divided by total population.

$\frac{150}{500} \\= 0.3$

The frequency of hba allele is equal to

$\sqrt{0.3} \\= 0.5477$
