A homozygous strain of plants (P1) has a mean height of 12 cm. A second homozygous strain of the same species (P2) has a mean height of 36 cm. When plants from the two strains are crossed together, the F1 plants have mean height of 24 cm. The F2 generation from the F1 X F1 crosses shows a wide range of heights; the majority are like the F1 plants, but 4 of 1000 are only 12 cm high (shortest), and 4 of 1000 are 36 cm high (tallest). 1. How many gene pairs are involved? a. 2 b. 4 c. 6 d. 8
