Question

when mendel crossed the two hybrid purple plants, what percent of the offspring had the dominant form of the trait? 0 50 75 25 100

Explanation:

Step1: Recall Mendel's Hybrid Cross

Hybrid purple plants (let's say genotype \( Pp \), where \( P \) is dominant for purple, \( p \) is recessive for white) are crossed. The Punnett square for \( Pp \times Pp \) is:

	\( P \)	\( p \)
\( p \)	\( Pp \)	\( pp \)

Step2: Determine Dominant Trait Offspring

Dominant trait (purple) is expressed in \( PP \), \( Pp \), \( Pp \). So out of 4 offspring, 3 have the dominant trait. To find the percentage: \( \frac{3}{4} \times 100 = 75\% \).

Answer:

75
