Parent 1 : AACCRR Parent 1 : Colored with anthocyanin pigment
Parent 2 : aaccrr Parent 2 : colorless (without anthocyanin pigment
F1 : AaCcRr F1 : Colored with anthocyanin pigment
Answer 3 :
It is obtained by crossing AaCcRr & AaCcRr
Each Parent will produce 8 gametes (ACR, ACr, Acr, AcR, aCR, acR, ...
Complimentary gene is interallelic interaction in which metabolic product of one gene compliment the metabolic product of another gene. If any one of them is absent, phenotypic expression fails to appear.
