In canaries, feather length is determined by a sex-linked gene at the G locus with two alleles. The wild-type allele produces long feathers while the dominant allele results in short feathers. An autosomal locus determines feather density (called plumage) where the dominant A allele causes dense plumage. A long-feathered female with thin plumage mates with a male that has short feathers and a dense plumage. Their first chick is a female with long feathers and thin plumage. a) What is the genotype of the male parent in this cross?  b) If the next chick is a male, what is the probability of him having short feathers and thin plumage?  c) A chick is caught that is pure-breeding for long feathers and dense plumage. However, you believe this chick was not from these parents. Provide a reason that supports your idea.

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.
