Epistatic and hypostatic gene
WebMay 22, 2009 · Epistasis, in the classical sense, provides a logical framework for inferring biological pathways from biochemical and other experiments, because it suggests that two genes are working within the same pathway and sometimes in what order they act. WebThe gene that has masking effect is called epistatic gene, and the gene whose effect is masked is known as hypostatic gene. Epistasis leads to modification of normal dihybrid or trihybrid segregation ratio in F2 generation. The term epistasis was coined by Bateson in 1909. Various types of epistatic gene

WebFeb 25, 2013 · Dominant Epistasis. (12:3:1) Dominant allele (eg.,A) of one gene hides the effect of allele of another gene (eg., B) and expresses itself phenotypically. The B allele (hypostatic) will be expressed only when gene locus A contains two recessive (aa) alleles. Thus, the genotype AA BB or Aa Bb and AA bb or Aa bb produce the same phenotype … WebA gene that is expressed in all of a population with the gene.

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. The alleles determining whether the dog is black or brown, are that of the hypostatic gene in this event. organza flower belt
