Ferrets are diploid organisms. You are tracking two phenotypes in ferrets: tail length and fur color. The single gene that controls tail length (gene T) is on chromosome 2 and unlinked from the single gene that| controls fur color (gene B), which is on chromosome 4. Brown is the dominant fur color and white is the recessive fur color. Long is the dominant tail length and short is the recessive tail length. Both genes are autosomal. You cross a true-breeding brown fur, short tail ferret to a true-breeding white fur, long tail ferret. nat are the expected phenotypes of the F1 progeny? You cross two F1 siblings to one another. Of the F2 progeny with the phenotype combination of brown fur and long tail, what proportion of the progeny are true-breeding for both traits
