Project #13603 - Mendel's Laws of Inheritance - Punnett Squares

Two Questions:

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. (8 marks).

2) In guinea pigs, the brown coat (B) is 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. (7 marks).
