Genetics problem help

Post by georgina009 » Mon Mar 10, 2008 2:12 am

I have been given a problem to do with crosses and stuff. I have done it but i got a weird answer so I wonder if you could help me:

C - coloured feathers
I - blocks expression of C
c - white feathers
i - dosent block C

Leghorn chicken - CCII
Wyandotte - ccii

Qn - What propotion of the F2 progeny obtained from crossing those two above will have white feathers?
My answer - 13:3
Am I correct? What do you get?
