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.
The fundamental unit of the organism, the cell contains various organelles with specialized functions and roles. The plasma or cell membrane separates the cell structure.
<h3>What is plasma or cell membrane?</h3>
Cell or the plasma membrane is the cell structure that is seen in the cells that separate the outer cell surroundings from the inner environment of the cell.
They allow the semipermeable passage and transportation of the substances in and out of the cell and are made up of lipid bilayer. It protects the cell from the invasion of bacteria and other microbes.
Therefore, option A. plasma or cell membrane separates the inner and the outer environment of the cell.

Answer:
radio waves and lightwaves
Explanation:
Radio waves and light waves are both types of electromagnetic waves in the electromagnetic spectrum. Radio waves and light waves travel a particular distance and hence, are used to convey information over distances.
Based on this question, radiowaves and light waves are both tools used to send information. Radiowaves carry information from the station to the receiver, likewise light waves from one medium to another.
