Result The fiber color was controlled by 4 pairs of genes at least. Whether the long fiber and linter were brown was controlled by a pair of dominant genes separately, the type of its fiber color was controlled by 2 pairs of minor genes at least, showing different types such as light brown and brown approaching white. The long fiber in F2 generation had 3 phenotypes altogether of brown long fiber and brown linter, white long fiber and white linter, white long fiber and brown linter, showing there was interaction among genes and the expression of dominant gene in brown long fiber inhibited the expression of recessive gene of linter color.
