In cotton, the dominant allele of the B gene determines the brown color of the fiber, the b allele – white. Gene A suppresses the appearance of brown and white coloration and causes green coloration of the fiber. The recessive allele does not affect the expression of fiber coloration. Determine what color the fibers of hybrids obtained from crossing plants with genotypes (females) Aabb and (male) aaBb will have.
The color of the fibers of the hybrids can be green, brown and white in a ratio of 2: 1: 1.
