In a cross between snails of the species Lymnaea peregra, the parental female comes from a true breeding sinistral line and the parental male comes from a true breeding dextral line. F1 offspring are crossed to each other. What proportion of the F2 offspring will be sinistral? 0% Oa, 25% Ob. 50% 75% d. 100% е.

Give an example of a monohybrid cross and a dihybrid cross.

Given the cross AaBbCc x Aabbcc, what is the probability of obtaining an offspring with the genotype aabbCc?

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.
