4. Wild mustard, like many plants, have small hairs called trichome on the surfaces of their stems and leaves. These are proposed to protect them from wind. This trait can be measures as hair count with is the number of hair per square cm of leaf area. You have two different true-breeding strains of wild mustard: Williams' Pride: This strain has hairs with a hair count of 60. Lauffer's Least: This strain is completely hairless (hair count = 0). When Williams' Pride is crossed with Lauffer's Least, the F₁ generation has a hair count of 30. When the F₁ is self-crossed the F2 plants are as follows: 1/16 with a hair count of 60 4/16 with a hair count of 45 6/16 with a hair count of 30 4/16 with a hair count of 15 1/16 with a hair count of 0 Make up an additive polygenic model to explain these results.
