Epistasis

Question 1

It is a genetic phenomenon where the effect of one gene depends on the presence of another.

Answer 1

Epistasis.

Question 2

It is the gene that does the masking.

Answer 2

Epistatic gene.

Question 3

It is the gene whose effect is masked.

Answer 3

Hypostatic gene.

Question 4

What is the difference between Dominance and Epistasis?

Answer 4

in DOMINANCE, interaction occurs WITHIN a single gene pair.(intra-allelic).

in EPISTASIS, interaction occurs BETWEEN DIFFERENT GENES. (inter-allelic).

Question 5

In ________ __________, a dominant allele (e.g., A) at one gene locus masks or suppresses the expression of another gene (e.g., B), regardless of what allele is present at the second gene locus.

Answer 5

Dominant epistasis.

Question 6

In _________ _________, the homozygous recessive alleles (bb)at one gene locus mask the effect of another gene (C) at a different locus.

Answer 6

Recessive epistasis.

Question 7

Also called complementary genes, refer to a type of gene interaction where two different genes work together to produce a specific phenotype.

Answer 7

Duplicate Recessive Genes.
