You will research major earthquakes and pick one to answer the following questions:
levacccp [35]
Research major earthquakes on google, or another website. I would go with question 1, Where is your earthquake? I would do the Haiti earthquake where the earthquake is in Haiti. Do more research on Google, because I cannot provide you with a link to an article because Brainly will not allow me to do so. Just research "major earthquakes" in Google and you will be good to go. Hope this helped!

The gene frequency for a dominant allele is 0.68 and the recessive allele is 0.39. What percent of the population has a homozygo
Alinara [238K]

Answer:

15.21 %

Explanation:

If we recall the basic formula of Hardy-Weinberg's equilibrium ; we have the following below:

p + q = 1

p² + 2pq + q² = 1

where;

p = frequency of the dominant allele in the population

q = frequency of the recessive allele in the population

p² = percentage of homozygous dominant individuals

q² = percentage of homozygous recessive individuals

2pq = percentage of heterozygous individuals

Given that p= 0.68 and q = 0.39

the percentage of the homozygous recessive genotype (q² ) will be

(0.39)² = 0.1521

= 0.1521 × 100

= 15.21 %

∴ the percentage of the population that has a homozygous recessive genotype = 15.21 %
