What is dominant epistasis?
It is a type of epistasis in which the dominant allele of one gene masks the expression of another gene.
It is a type of epistasis in which the recessive allele of one gene masks the expression of another gene.
It is a type of epistasis in which the expression of one gene is completely dependent on the expression of another gene.
It is a type of epistasis in which two genes interact to produce a novel phenotype.
Answers (1)
Dominant epistasis occurs when the presence of a dominant allele at one gene locus masks the expression of a different gene. In other words, the effect of the dominant allele on one gene masks the expression of the gene at another locus. Dominant epistasis is a type of genetic interaction where the presence of a dominant allele at one locus (the epistatic gene) masks the expression of alleles at another locus (the hypostatic gene). This means that the presence of the dominant allele at the epistatic gene can override the effects of the alleles at the hypostatic gene, resulting in a modified phenotype. Hence option A is the correct answer.
Option(B) Dominant epistasis is a type of epistasis in which the dominant allele of one gene masks the expression of another gene. Hence option B is incorrect.
Option(C) Dominant epistasis is a type of epistasis in which the dominant allele of one gene masks the expression of another gene. Hence option C is incorrect.
Option(D)Dominant epistasis is a type of epistasis in which the dominant allele of one gene masks the expression of another gene. Hence option D is incorrect.
