Question

in pea plants purple flowers are dominant, white flowers are recessive. use the allele f to represent your genotypes.

1. if two white flowered plants are crossed, what percentage of their offspring will be white flowered?

ff × ff
probabilities
punnett square

Explanation:

Step1: Analyze the genotypes of parents

Since white flowers are recessive, the genotype of each white - flowered parent is \(ff\).

Step2: Construct the Punnett square

When crossing \(ff\times ff\), the Punnett square has all cells with \(ff\) genotype.

Step3: Determine the phenotype percentage

The phenotype of \(ff\) is white. Since all offspring have the \(ff\) genotype, the percentage of white - flowered offspring is \(100\%\).

Answer:

The percentage of their offspring that will be white - flowered is \(100\%\).
