| The blue-eyed right-hander, whose father was left-handed, married a brown-eyed left-hander from a family all of whom had brown eyes for generations. What phenotypes can they give birth to children?
Right-handers are dominant, while left-handers are recessive. Brown eyes are also dominant.
A – right-handed, a – left-handed,
B – brown eye color, b – blue.
The father will be heterozygous in the first place, because his father was left-handed, his mother is homozygous for the latter, because there were no blue-eyed in her family.
Scheme for solving the problem:
Parents: Aabb x aaBB,
Gametes: Ab, ab x aB,
Children: AaBb (right-handed with brown eyes), aaBb (left-handed with brown eyes).
