Question

Given appropriate biological/technical terms for the following:
The suppressed allele of a gene.

Answer 1

Hint: Epistasis is the process of genetics in which the presence or absence of one gene affects the gene mutation or expression of other gene, or one gene masks the effect of another gene. The genes are of two types: dominant and recessive genes.

Complete answer:
The allele that is suppressed is known as the recessive allele. The expression of this recessive allele is masked by the presence of the dominant allele and thus the offsprings will most probably carry the traits that were transferred from the dominant allele while the traits that were transferred from the recessive allele will be shown in the second filial generation or after several generations. Its genetic code does not have the tendency to produce a phenotype when the dominant allele is present. If a person is having a certain trait then it must be that the person must contain the two alleles of the same trait from both the two parents.

Additional information
Epistasis is adapted from Greek meaning “standing upon.” The allele that masks the expression of the other allele is called epistatic alleles while the other one that is masked is called the hypostatic alleles.
There are two types of Epistasis: Recessive epistasis and Dominant epistasis.
The masking of expression of one allele at one locus by the recessive allele at another locus is called the recessive epistasis. It needs two copies of the same allele. As an example, If the allele for blue eyes is recessive, then the person requires two similar alleles of it for blue eyes to possess. when the two recessive alleles combine together to express a recessive phenotype then it is said to be a homozygous recessive.
When one gene masks the effects of the other gene or allele then it is called the dominant epistasis. The phenotypic ratio in ${F}_{2}$ generation is 12:3:1 or 13:3

Note:
Epistasis is adapted from Greek meaning “standing upon.” In 1882-1884 the transmission of the dominant and the recessive alleles was discovered by scientist Gregor Mendel in his law of segregation. This can be carried from one generation to another through the process of sexual reproduction.
