Question

In 400 individuals, the frequency of a recessive allele is 40%. Find out which of these represents the total number of individuals with dominant phenotype?
A. 144
B. 192
C. 256
D. 336

Answer 1

Hint: The two genes code for a similar adaptation of an attribute when the aggregate will coordinate the genotype. Assuming the two qualities bear the numerous varieties for the detail and the entirety will be controlled by the dominant gene. For example, brown-colored eyes' quality is chief, while the gene for blue eyes is recessive.

Complete answer: In the number of inhabitants of 400 people, if 40% is a recessive allele, then 60% will be the dominant phenotype (144).
A recessive allele is fundamentally a genetic code that does not make any aggregate if there is a dominant allele. Various alleles produce somewhat multiple proteins, which work in numerous ways. In predominant/recessive connections, the recessive allele delivers a non-utilitarian protein. It is a specific portion of DNA. At the same time, a dominant allele is the one that makes a particular aggregate in any event when a passive allele is available.
It is feasible for latent qualities to be the most well-known or prevailing characteristics to be uncommon. One-way rate can go from recessive to dominant with another DNA contrast that is predominant and causes a similar attribute.
Hence, Option (A) 144 is the correct answer.

Note:
In 400 individuals, 60%, i.e., 144 individuals, contribute to the absolute number of people with predominant aggregate. Predominance influences the phenotype derived from a creature's qualities. However, it does not affect how these qualities are acquired. Full strength happens when the heterozygote aggregate is undefined from that of the homozygous parent. Recessive alleles possibly express their aggregate if a life form conveys two indistinguishable duplicates of the recessive allele, which means it is homozygous for the recessive allele.
