Afarmer mates a bull that is homozygous dominant for color (bb) and heterozygous curly for coat (cc) with a cow that is homozygous white for color (bb) and homozygous for a straight coat (cc). what is the percent chance of the offspring having a white curly coat?

Zero %

Explanation:

Male is BBCc and  Female is bbcc , then

BBCc x bbCc will always give the B allele in all the F1 generation combinations.  That is, all individuals will be coloured, although a half can be straight coat.

If you use a Punnett square, it will be easy to visualize the cross

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
