Collaborator Genes

These are Genes that present in the chromosomes shows intergenic interaction. These genes located in 2 loci controlling the same trait and interact to produce some totally new traits or phenotypes that neither of the genes alone can produce the inheritance.

Eg: Comb pattern in Poultry [9:3:3:1]

The genes involved are RRpp for Rose Comb and rrPP for Pea Comb. These interact and modify the single comb, basic type of comb pattern to walnut type.

The Progenies Phenotypes are

Walnut Comb = 9

Rose Cob = 3

Pea Comb = 3

Single Comb = 1
