WebThe correct answer to question 33 is "E. two," which refers to recessive epistasis. This is due to the fact that research on the two genes responsible for flower color includes one gene that regulates the color intensity (R for red and r for yellow), and another gene that governs the synthesis of color pigments (P for pigment and p for no ...

WebRecessive alleles at one locus (aa) mask the phenotypic expression of other gene locus (BB, Bb or bb) such epistasis is called recessive epistasis. The alleles of ‘B’ locus express themselves only when epistatic locus ‘A’ has dominant allele like AA or Aa. The phenotypic ratio is 9: 3: 4. Example: Web2) Dominant epistasis (12:3:1) 3) Dominant and recessive (inhibitory) epistasis (13:3) 4) Duplicate recessive epistasis (9:7) 5) Duplicate dominant epistasis (15:1) and 6) Polymeric gene interaction (9:6:1).

WebFigure 3.23 shows a classic case of epistasis, which signifies some alteration in the basic 9:3:3:1 phenotypic ratio expected from a dihybrid cross. In the case shown, we are looking at a single phenotypic trait (pea flower color) that is determined by two independent genes. ... If the crossing of two homozygous recessive "mutant" strains (for ...
WebFinally, epistasis can be reciprocal such that either gene, when present in the dominant (or recessive) form, expresses the same phenotype. In the shepherd’s purse plant ( Capsella bursa-pastoris ), the characteristic of seed shape is controlled by two genes in a dominant epistatic relationship.
WebRecessive epistasis. The presence of recessive alleles at one locus makes useless the presence of dominant alleles at another locus. This happens if two enzymes are needed in series; "the chain breaks" if either link fails. The Mendelian ratio of a dihybrid cross is 9:7.
