As a hypothetical example, a trait in mice results in abnormallylong tails. You initially have a true-breeding strain with normaltails and a true-breeding strain with long tails. You then make thefollowing types of crosses:Cross 1: When true-breeding females with normal tails arecrossed to true-breeding males with long tails, all F1 offspringhave long tails.Cross 2: When true-breeding females with long tails arecrossed to true-breeding males with normal tails, all F1 offspring have normal tails.Cross 3: When F1 females from cross 1 are crossed to true-breeding males with normal tails, all offspring have normal tailsCross 4: When F1 males from cross 1 are crossed to truebreeding females with long tails, half of the offspring havenormal tails and half have long tails.Explain the pattern of inheritance of this trait.

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.
