The trait of feathering in fowls is a sex-limited trait controlled bya single gene. Females always exhibit hen-feathering, as do HHand Hh males. Only hh males show cock-feathering. Startingwith two heterozygous birds that are hen-feathered, explain howyou would obtain a true-breeding line that always produced cockfeathered males.

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.
