Question

A plant with round seeds is crossed with another plant with round seeds. Round are dominant over oval seeds. When two heterozygous round-seeded plants are crossed, what is expected of their offspring, assuming random chromosome segregation?

Answer 1

the outcome will be 25% homozygous dominant, 50% heterozygous, and 25% homozygous recessive. so a 75% chance they will have round seeds and a 25% chance they will have oval seeds.
