In a guinea pig, curly coat dominates over smooth. Determine the genotypes of all animals in the following

In a guinea pig, curly coat dominates over smooth. Determine the genotypes of all animals in the following crosses: a) ♀ curly X ♂ smooth; F1 – all curly b) P ♀ curly X ♂ smooth; F1 – 50% curly, 50 smooth. C) P ♀ curly X curly; F1 – 25% smooth, the rest are curly

According to Mendel’s second law, the first generation will be dominant. In this case, the dominant feature is curly coat, the recessive feature is smooth.
1.P: ♀ curly X ♂ smooth;
G: AA x aa;
F1: Aa;
2. P: ♀ curly X ♂ smooth;
G: Aa x aa;
F1: Aa, aa;
3. P: ♀ curly X ♂ smooth;
G: aa x aa;
F1: aa.
