A wife with big eyes and a straight nose and a husband with small eyes and a Roman nose had children, some of whom had small eyes and a straight nose. A – big eyes, a – small eyes;
B – Roman nose, b – straight nose Recessive symptoms appear only in the homozygous state (small eyes – aa, straight nose – bb). Since some children had small eyes and a straight nose, their parents were heterozygous for the dominant characteristics. PP g Aabb (b, n) x m aaBb (m, p)
