NAME "- -. I - - [ Question 1. 5 POINTS, tn Labrador retrievers, two loci control coat color: Band E. Black dogs have dominant alleles at both loci (B_E_); brown dogs have bbE_, and yellow dogs can be either B_se or bbee. A) 2 points You cross a dihybrid black dog (BbEel with a monohybrid yellow dog (Bbee) (PARENT generation). Draw a Punnett Square showing the gametes produced by each parent in this cross, and how they combine to form the genotypes of the possible progeny (F1 GENERATION).
