Similarly it is not good to gain excess weight while in the pregnancy stage, as the baby might grow at a larger proportion that required.
Answer:
<em>The offspring which carries the allele II will be homozygous dominant.</em>
Explanation:
A dominant trait can be described as a trait which masks the effect of a recessive trait. A recessive trait can be described as a trait which gets masked by the dominant trait.
A homozygous dominant trait occurs when both the alleles for the gen are dominant. A heterozygous dominant trait occurs when one allele is dominant and the other is recessive for the trait.
Hence, a homozygous dominant trait will carry the alleles II.
If you are referring to selection pressure, when the selection pressure decreases, there will be weaker forces of natural selection. The angler fishes without the favourable traits would not be that strongly selected against and vice versa. In some cases such as predation selection pressure, the population of angler fishes in the habitat may increase
