Question

In pea plants, purple flowers (F) are dominant over white flowers (f). If two white flowers are crossed, what percentage of the offspring will be white flowers

Answer 1

When two white-flowered pea plants are crossed and both are homozygous recessive (ff), all of their offspring will also be homozygous recessive (ff) for flower color. Therefore, 100% of the offspring will have white flowers.

Answer 2

Given white flowers are the recessive colors, we can construct a punnett square to find that 100% of the offspring will be white flowers.
