I don't think so because plants need carbon dioxide, and when plants get carbon dioxide they let off oxygen. So without carbon dioxide the plants can't give us oxygen.

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 %
