Question

1. in pea plants purple flowers are dominant to white flowers. if two white flowered plants are cross, what percentage of their offspring will be white flowered?

Explanation:

Step1: Determine the genotype of white - flowered plants

Since white flowers are recessive (let the allele for purple be \(P\) and for white be \(p\)), white - flowered plants must have the genotype \(pp\).

Step2: Cross the two white - flowered plants

When we cross \(pp\times pp\), using the Punnett square method:

Gametes of first parent	Gametes of second parent
\(p\)	\(pp\)
\(p\)	\(pp\)

All of the offspring will have the genotype \(pp\).

Answer:

100%
