Salamanders have a male heterogametic system for sex determinations where females are ZZ and males are ZW. The allele for the color of the tail is sex linked and the red allele is found on the W chromosome and the blue allele is found on the Z chromosome. You mate a male and female and they have 3 female offspring. What is the phenotypic ratio for tail color for their offspring? Group of answer choices 2 Blue : 1 Red 0 Blue : 3 Red 1 Blue : 2 red 3 Blue : 0 Red
