Question
Please help me!!!! I need help with this practice test question.
In Guinea pigs, the brown coat (B) is a dominant over the cream-coloured coat (b), and straight hair (H) is dominant over curly hair (h). Using a Punnett square, complete the cross between a heterozygous brown, curly-haired individual and a cream-coloured, homozygous straight-haired individual. State the parent genotypes, gametes, and the F1 Phenotypes and genotypes.

Bbhh and bbHH, so second parent can only give bH gametes. Use Punnett square to take it from there.
