Question

6 if a white - flowered pea plant (ww) is crossed with a heterozygous purple - flowered plant (ww), what will their offspring look like? multiple choice all of the offspring will be purple - flowered heterozygotes half the offspring will be purple - flowered heterozygotes, and half will be white - flowered one - quarter of the offspring will be purple - flowered homozygotes, half will be purple - flowered heterozygotes, and one - quarter will be white - flowered all of the offspring will be white - flowered homozygotes

Explanation:

Step1: Determine the gametes

The white - flowered plant (ww) can only produce gametes with the allele \(w\). The heterozygous purple - flowered plant (Ww) can produce gametes with either \(W\) or \(w\).

Step2: Create a Punnett square

	\(W\)	\(w\)
\(w\)	\(Ww\)	\(ww\)

From the Punnett square, we can see that half of the offspring have the genotype \(Ww\) (purple - flowered heterozygotes) and half have the genotype \(ww\) (white - flowered).

Answer:

Half the offspring will be purple - flowered heterozygotes, and half will be white - flowered.
