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

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
