Question

Difference between epistatic and hypostatic genes

Answer 1

Hypostatic gene. A hypostatic gene is one whose phenotype is altered by the expression of an allele at a separate locus, in an epistasis event. Example: In labrador retrievers, the chocolate coat colour is a result of homozygosity for a gene that is epistatic to the "black vs. brown" gene.

Epistasis is an interaction between non-allelic genes present in the different locus. Epistatic gene is the gene which supress the other gene and the gene which has been suppressed is called hypostatic gene. ... so, cc is the recessive but a epistatic gene and A gene is the hypostatic gene to cc.

Answer 2

The masking of the phenotypic effect of alleles at one gene by alleles of another gene. A gene is said to be epistatic when its presence suppresses the effect of a gene at another locus. Epistatic genes are sometimes called inhibiting genes because of their effect on other genes which are described as hypostatic.

A hypostatic gene is one whose phenotype is altered by the expression of an allele at a separate locus, in an epistasis event. Example: In labrador retrievers, the chocolate coat colour is a result of homozygosity for a gene that is epistatic to the "black vs. brown" gene.
