Which of the following describes the genotype if you crossed two black and white (BW) chickens?

Question

1. 
   
2. 100% BW
3. 
   
4. 50% BB 
5. 50% WW
6. 
   
7. 50% black
8. 50% white
9. 
   
10. 100% black and white

Answer 1

You can draw a Punnett Square, with both sides of the Punnett Square saying BW. From there, you can fill in the Punnett Square to get the ratio of BB, BW, and WW. You can then determine the phenotype of the offspring chicken from the genotype, depending on whether black or white is dominant or recessive.
