Question

when considering flower color, p = purple and p = white.
in mendel’s monohybrid cross of a homozygous recessive parent pea plant and a homozygous dominant parent pea plant, consider the first set of offspring (the f1 generation). after completing a punnett square, which of the following would describe the correct phenotype of the offspring? (aks 7e)
a showed the phenotypes of purple and white flowers.
b showed purple and white striped flowers.
c showed only white flowers.
d showed only purple flowers.

Explanation:

In Mendel's monohybrid cross for flower color, the dominant allele (P for purple) masks the recessive allele (p for white) in the heterozygous offspring (F1 generation) of a homozygous dominant (PP) and homozygous recessive (pp) cross. The offspring will have the genotype Pp, and since purple is dominant, their phenotype will be only purple flowers. Option A is incorrect as the F1 generation doesn't show both phenotypes (that's in F2). Option B is incorrect as there's no striped phenotype. Option C is incorrect as white is recessive and masked.

Answer:

D. Showed only purple flowers.
