Question: In durum wheat, two varieties exist: one variant with spring growth habit and another variant with winter growth habit. Two true breeding plants with spring

In durum wheat, two varieties exist: one variant with spring growth habit and another variant with winter growth habit. Two true breeding plants with spring growth habit were crossed. The resulting F1 were self-crossed to generate the following F2 plants:

spring growth: 85

winter growth: 6

a. What is the pattern of inheritance seen here? [ Select ] ["Recessive Epistasis", "Codominance", "Additive", "Redundancy", "Dominant Epistasis"]

b. State the genotype of the parents. [ Select ] ["AaBb AND aabb", "AAbb AND AAbb", "AAbb AND aaBB", "aaBB AND AABB", "AABB AND aabb"]

c. What are the genotypic ratios of the F1 plants? [ Select ] ["AaBb:Aabb: aaBb: aabb = 1:1:1:1", "AABB: AaBb: aabb = 1:2:1", "All AABB", "All aabb", "All AaBb"]

d. What are the phenotypic ratios of the F1 plants? [ Select ] ["Spring : Winter = 2:1", "All Spring growth", "Spring : Winter = 3:1", "Spring : Winter = 1:1", "All Winter growth", "Winter : Spring = 3:1"]

e. Give the phenotypic ratios of the F2 plants. [ Select ] ["Spring: Winter = 15:1", "Spring : Winter = 1:1", "Winter:Spring = 13:3", "Spring : Winter = 9:7", "Spring: Winter = 13:3", "Winter: Spring = 15:1"]
