Question

What conclusions can you draw about the results of your first cross, between a homozygous red bull (RR) and a heterozygous red cow (Rr)?

Answer 1

Imagine this. Below is a punnett square.
r R
R | rR | RR|
R | rR | RR|

So the conclusions are that there is a 50% chance of it being homozygous, or heterozygous cow. Both would be red, because the red gene is dominant in both outcomes.

Hope this helps.
