At which stage in development would a cell's gene expression not be altered between cell types? a) pre-gastrulation b. All of these are correct c. blasula d. post-fertilization e. zygote 2. Dihybrid crosses: In dogs, black coat color(B) is dominant to yellow coat fur (b), and straight fur (F) is dominant to curly fur (f). The coat color gene and the fur texture gene are on different chromosomes, so they assort independently, and are not sex linkied. Determine the ratio of having a yellow dog with straight hair if the parents are: BbFF x Bbff a. What are the phenotype of the parents? b. Complete a punnet square. List all the genotypes of the predicted offsprin of this mating c. Based on your Punnet sqaure, list all the genotypes for offspring that would yield a dog with yellow straigh hair d. Based on the punnet square, what is the predicted phenotypic ratio for those parents having a dog with black curly hair.
