Question

The following seed phenotypes showed up in a generation of plants. Which alleles are recessive? blue round = 75 white round = 28 blue wrinkled = 24 white wrinkled = 8 blue and round white and round blue and wrinkled white and wrinkled

Answer 1

Answer:

blue and wrinkled are recessive.

Explanation:

Answer 2

Based on the given seed phenotypes, the alleles that are both recessive include: D. white and wrinkled.

What is a recessive trait?

A recessive trait can be defined as a masked allele in the genotype which can only expressed by a living organism when two (2) of the same masked alleles are inherited.

In Genetics, the phenotypic ratio between the offspring of two (2) heterozygous parents within the F2 generation is equal to 9:3:3:1.

Given the following seed phenotypes:

• Blue round = 75 = 75/9 ≈ (9 × 8).

• White round = 28 = 28/3 ≈ (3 × 8).

• Blue wrinkled = 24 = 24/3 ≈ (3 × 8).

• White wrinkled = 8 = 8/1 ≈ (1 × 8).

Therefore, the phenotypic ratio between the offspring is close to 9:3:3:1 within the F2 generation.

Note: 1 represents the number of phenotypes with both recessive traits.

In conclusion, we can logically deduce that white and wrinkled are the alleles that are both recessive.
