A strain of plants has a mean height of 24 cmcm. A second strain of the same species from a different geographical region also has a mean height of 24 cmcm. When plants from the two strains are crossed together, the F1F1 plants are the same height as the parent plants. However, the F2F2 generation shows a wide range of heights; the majority are like the P1P1 and F1F1 plants, but approximately 4 of 1000 are only 12 cmcm high, and about 4 of 1000 are 36 cmcm high How much does each gene contribute to plant height? Express your answer as an integer.

Question

A strain of plants has a mean height of 24 cmcm. A second strain of the same species from a different geographical region also has a mean height of 24 cmcm.

When plants from the two strains are crossed together, the F1F1 plants are the same height as the parent plants.

However, the F2F2 generation shows a wide range of heights; the majority are like the P1P1 and F1F1 plants, but approximately 4 of 1000 are only 12 cmcm high, and about 4 of 1000 are 36 cmcm high

How much does each gene contribute to plant height?
Express your answer as an integer.
