You have a beef cow that is bbPp and you mate it to a bull of BbPp where B=Black hair coat, b=red hair coat and P=polled and p=horned. Using the punnet square method, answer the following questions:
1. What Percentage of the offspring would be black with horns?
2. If B was only partially dominant to b then the resulting color would be ROAN, a mix of black and red. What percent of the offspring would be roan in color with horns. |

Term
| IF you mate a bull with genotype Aa bb Cc Dd to a cow of genotype Aa Bb Cc Dd and you know that all contributing genes from this cross will add 700 lbs of milk to the base of 17,00 lbs, what will be the milk production from the lowest producer and highest producer from this cross, in that order? |
|
Definition
| Due to the fact that we have 7 contributing genes (capital letters) we would multiply 7 times 700 lbs = 4900 lbs of milk. You would then add 17,000 lbs which equals 21,900 pounds. 21,900 pounds is our maximum. Next we would see if we had anymore contributing genes, which we don't so our minimum milk production is 17,000. |

Term
| If I have a stallion and he provided 60 ml of semen at a concentration of 200 x 10^6 sperm/ml with a 65% motility rate and 100% normality, how many mares could be bred using his semen by using 500,000,000 sperm per insemination? |
|
Definition
| You would want to multiply 60 x 200= 12,000 x 10^6 (total # of sperm) then you would multiply 12,000 by the motility rate which is .65= 7800 x 10^6. You would then divide 7800 x 10^6 by 500 x 10^6 = 15.6 per insemination |
