What conclusions can you draw about the results of your second cross between a heterozygous red bull (rr) and a heterozygous red cow (rr)?

In the result obtained in f1 generation of mendel's monohybrid cross,both dominant and recessive characters are present. They both remain together for long time but they donot intermix to each other. They separate out only at the time of formation of gamets.

So, I believe that the first generation will be 50% homozygous dominant
and 50% heterozygous. (hope this helps)
