The following points highlight the eight important forms of gene expressions and interactions. The forms are: 1. Typical Di-Hybrid Ratio 2. Complementary 3. Supplementary 4. Polymerism 5. Epistatis 6. Inhibitory 7. Duplicate 8. Cumulative or Additive. Form # 1. Typical Di-Hybrid Ratio (9:3:3:1): This type of gene interaction produces the typical di-hybrid ratio of 9:3:3:1 in F2 for a single [...]
In this article we will discuss about:- 1. Meaning of Gene Interactions 2. Characteristics of Gene Interaction 3. Gene Interaction for Comb Shape in Poultry. Meaning of Gene Interactions: When expression of one gene depends on the presence or absence of another gene in an individual, it is known as gene interaction. The interaction of genes at different loci that [...]
