VladimirAG [237]

Answer:

Option 1, 0

Explanation:

Complete question

Flower color in the varieties of pea plants studied by Mendel is controlled by alleles at a single locus. A group of peas homozygous for purple flowers is grown in a garden. All flowers are purple, yet there is some variation in the intensity of the purple color. The estimated heritability for this observed variation in flower color would be

  1. 0.
  2. 0.5.
  3. 0.75.
  4. 1.
  5. Cannot be determined without additional information

Solution

Given all the pea plants in the garden are homozygous purple (PP)

If we cross two PP parents, the following offspring will be produces

PP * PP

PP, PP, PP, PP

This means that all offspring are also homozygous purple.

Thus, chances of inheriting variation in the purple color of offspring are negligible. However, the variation in their color can be due to their individual interaction with the variable factors in the environment

Hence, option 1, 0 is correct
