A Sheldon moment

I think I might have troubles trusting my education to this professor after hearing this slip up. And I might have spoken up in class were this my own instructor.

I was trolling the internet for help in solving a genetics problem (stupid dyhybrid crosses). I found this example, and believe me, you all should be able to tell me the answer to this problem. (Come on, Ej, I'm really depending on you here to answer this one...)

• A farmer just bought a black cow.

• Black (B) is a dominant color. White (b) is recessive.

• The black cow mates with a white steer on several occasions.

• 2 of the offspring are white & one is black.

• Create a chart or Punnett Square that shows what the black cow’s genotype must be.


Um, the answer should be NO OFFSPRING! One of the cows was a steer! I tell ya, sometimes academics are idiots! But it gave me a good laugh.

Unfortunately, I still need help with the assignment.
