Question

The following results were obtained from a dihybrid cross between two pea plants:

 

315 plants with round seeds and yellow flowers

101 plants with wrinkled seeds and yellow flowers

108 plants with round seeds and white flowers

32 plants with wrinkled seeds and white flowers

 

Assume that round seeds and yellow flowers are dominant and both parent plants were heterozygous for both traits.
