Answer:
The options
a. New combinations of genes yielding genotypes of greater fitness
b. Few heterozygotes because of underdominance
c. Frequency-dependent selection, leading to fluctuations in fitness
d. Heterozygotes with greater fitness, owing to overdominance
e. A random assortment of genotypes because of genetic drift
The CORRECT ANSWER IS b.
b. Few heterozygotes because of under dominance
Explanation:
In genetics, underdominance (at times called "negative overdominance") is the opposite of overdominance.
It is the selection against the heterozygote, that leads to disruptive selection and divergent genotypes. It occurs in cases of inferior and reduced fitness (As in our case study, it is the different chromosomal fusions and inversions)
of the heterozygotic genotype to the dominant or recessive homozygotic genotype. It is unstable as it causes fixation of either allele.
Another example is the African butterfly species Pseudacraea eurytus, which makes use of Batesian mimicry to avoid predation. This species carries two alleles that gives a coloration that is alike to a different local butterfly species that is harmful to its predator. The butterflies who are heterozygous for this trait are observed to be intermediate in coloration and thus encounter an higher risk of predation and a decrease in the total fitness.

Water-soluble vitamin excesses are swiftly eliminated in urine and infrequently build up to hazardous amounts.
What is water-soluble vitamins ?
The B vitamins — folate, thiamine, riboflavin, niacin, pantothenic acid, biotin, vitamin B6, and vitamin B12 — and vitamin C are the nine water-soluble vitamins. A clinical condition caused by a deficiency in one or more of these water-soluble vitamins can have serious morbidity and death effects.
The fat-soluble vitamins are used by your body as needed, and any extra is stored in your tissues and organs. The risk of vitamin poisoning increases when you take too much fat-soluble vitamins on a regular basis, making them more dangerous than water-soluble vitamins.
