Think about the problem of cone shape inheritance in chickens, where walnut, rose, pea, and single are observed as distinct phenotypes. Considering the following data, determine how comb shape is inherited and what genotypes are present in each cross:

Cross 1: single x single à all single

Cross 2: walnut x walnut à all walnut

Cross 3: rose x pea à all walnut

Cross 4: F1 x F1 of Cross 3

walnut x walnut à 93 walnut

28 rose

32 pea

10 single
