The eye ring color in wood ducks is under the control of a single, sex linked gene.  The dominant allele (R) produces a white eye ring and the recessive allele (r) produces a green eye ring.  Provide the results to the following crosses (note birds have ZZ:ZW sex determination). a)  Provide the phenotypes and phenotypic ratios of a cross between a female with a white eye ring and a male with a green eye ring. b)  Determine the phenotypes and phenotypic ratios for a cross involving an F1 female and an F1 male from the above cross.

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.
