In a pea plant ,violet flower are dominant to white flower .If heterozygous violet coloured plant is crossed with white coloured plant ,what ratio of violet and white plants would you expect in F1 generation ?

50:50

The correct answer is Option (3) –50:50

If a heterozygous violet-colored pea plant (Ww) is crossed with a white-colored plant (ww), the expected ratio of violet to white plants in the F1 generation is 50:50.

Here’s a detailed explanation:

• The heterozygous violet plant has the genotype Ww.
• The white plant has the genotype ww.

When we cross Ww with ww, the possible genotypes of the offspring can be determined using a Punnett square.

From the Punnett square, we see the following results:

• 50% of the offspring have the genotype Ww (heterozygous, violet flowers).
• 50% of the offspring have the genotype ww (homozygous, white flowers).

Since the violet flower color (W) is dominant over the white flower color (w), the phenotypes of the offspring will be:

• 50% violet flowers (Ww)
• 50% white flowers (ww)

Thus, the expected ratio of violet to white plants in the F1 generation is 50:50.
