Purple flowers (P) are completely dominant over white flowers (p) in pea plants. A plant that is heterozygous for purple flowers (male) is crossed with another plant that has white flowers (female). Use a Punnett square to determine the expected genotypic and phenotypic ratios for the offspring.

What is the purple pea plant's genotype?

What is the white pea plant's genotype?

What are the purple pea plant's gametes?

What are the white pea plant's gametes?

What is the expected genotypic ratio of the offspring?

What is the expected phenotypic ratio of the offspring?

Answer #1

Purple flowers (P)- completely dominant over white flowers (p) in pea plants.

Heterozygous male purple flowers- Pp

Homozygous female white flowers- pp

Using Punnett square,

P p
p Pp pp
p Pp pp

The purple pea plant's genotype is Pp.

the white pea plant's genotype is pp.

The purple pea plant's gametes are P and p.

The white pea plant's gametes are p and p.

The expected genotypic ratio and, phenotypic ratio of the offspring is same which is 2:2 = 1:1

In pea plants, the allele for purple flowers ( W ) is dominant to the allele for white flowers ( w ). To determine whether a plant with purple flowers is homozygous or heterozygous with respect to flower color, the plant should be crossed with another pea plant with what genotype and phenotype with respect to flower color?

When Mendel crossed pea plants that were true breeding for purple flowers (PP) with pea plants with white flowers (pp), all of the offspring had purple flowers.  When he let these offspring self-fertilize, he got purple and white second generation (F2) offspring in a phenotypic ratio of 3:1. But, we know that the genotypic ratio is really 1:2:1.  Why? (1 point)

In the datura plant, purple flower color is controlled by a dominant allele P. White flowers are found in plants homozygous for the recessive allele p.
