rusak2 [61]

1. The conclusion that can be made about the results of your first cross between a homozygous red bull (RR) and a heterozygous red cow (Rr) is shown below :
You supposed to make a punnet square, so (picture)
Than you will get that the first generation will be 50% homozygous dominant
and 50% heterozygous which lead us to conclusion :
Crossing results in 50% (dominant homozygote) and 50% (dominant heterozygote).

2. Conclusion about the results of your second cross between a heterozygous red bull (Rr) and a heterozygous red cow (Rr) is shown in the second picture. And you can see that in 25% (dominant homozygote), 50% (dominant heterozygote) and 25% (homozygous recessive).

3. Conclusion about the results of your third cross between a homozygous white bull (rr) and a homozygous white cow (rr) are shown in the third picture. In this case you can see the result of 100% (homozygous recessive).
