Use the pedigree to answer the question. How is this trait inherited? A. The trait is epistatic. B. The trait is X-linked. C. The trait is dominant. D. The trait is recessive.

Give written answer with explanation and conclusion  A cross was made between a white male dog and two different black females. The first female gave birth to eight black pups, and the second female gave birth to four white and three black pups. What are the likely genotypes of the male parent and the two female parents? Use Punnett’s squares to support your answer. Explain whether you are uncertain about any of the genotypes.
