A female fruit fly with vermilion eyes and normal wings is crossed with a male with normal red eyes and cut wings. The F₁ progeny consist of females with red eyes and normal wings, and males with vermilion eyes and normal wings. When the F₁ progeny are interbred, the F2 consists of two types of females-vermilion eyes, normal wings (1/2) and red eyes, normal wings (1/2), and two types of males- vermilion eyes, normal wings (1/2) and red eyes, cut wings (1/2). Are the genes for eye colour and wing type X-linked or autosomal? Both genes are X-linked. The eye-colour gene is X-linked and the wing-type gene is autosomal. The eye-colour gene is autosomal and the wing-type gene is X-linked. Both genes are autosomal. More than one of the choices is consistent with the data.

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.
