Question

Predict the offspring for a cross of true-breeding lineages (BBEE × bbee). Fill in the Punnett square with possible genotypes. a. BE, Be, bE, be b. BB, EE, bb, ee c. Bb, Ee d. Bb, Ee, Bb, Ee

Answer 1

A Punnett square can be used to predict the genotypes of offspring in a cross between two true-breeding lineages, BBEE and bbee. The possible genotypes in this cross would be Bb, BE, bE, and be.

Step-by-step explanation:

A Punnett square is a tool used in genetics to predict the possible offspring of a cross between two organisms. In this case, the cross is between two true-breeding lineages: BBEE and bbee. To fill in the Punnett square, we list all possible combinations of the parental alleles (Bb and Ee) along the top and side of the grid. The boxes in the table represent the possible genotypes of the offspring. In this case, the genotypes in the Punnett square would be Bb, BE, bE, and be. So the correct answer is (a) BE, Be, bE, be.
