1. The length of snakes can vary between 0.8m and 2.3 m long. Ina large population of snakes there were just 2 of 2.3m length outof 560 snakes. How many genes are involved in determining thischaracter?
2. A) The heights of two true-breeding strains of maize wereboth 1.75m and when crossed the F1 height was also 1.75m. Selfingthe F1 produced an F2 with a range of heights from 1.59 to 1.91m.Out of the F2 of 451 plants there were 25 of the tallest. If the F1was test-crossed, how many phenotypes would you observe?

3. In a cross of two trihybrids what would be the proportion ofoffspring carrying 3 dominant alleles?
Please shows the details in explanation,thx~
