Cross a P generation, LlBb with llbb. Assume the following F1 generation:LlBb: 480Llbb: 20llBb: 20llbb: 480Which offspring are not the recombinant offspring in this cross?

Respuesta :

It is mentioned in the question that we are crossing Tail-Feather Length and Feather Color with short feather length and recessive feather color organisms.

P1: LlBb X llbb

Gametes: LB: Lb: lB: lb : lb

Offspring:

LlBb: 480

Llbb: 20

llBb: 20

llbb: 480

So as we see that perntal combinations are LlBb and llbb which means 480 + 480 organisms are just like parents while Llbb: 20 and llBb: 20 (20 +20=40) are recombinants.

Answer: It means that number of recombinants are 40.
