Please help me with these homework questions.. Thanks

1. Consider a cross between a pea plant that is heterozygous for round seeds and a pea plant that has wrinkled seeds. The allele for round seeds (R) is dominant over that for wrinkled seeds (r). Using a Punnett square, determine the genotypes of the offspring.


2. 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 parents genotypes, gametes, and the F1 Phenotypes and genotypes.
