Mr. jones has blood type b and mrs. jones has blood type ab. what is the probability that they will have a child with blood type a if both of mr. jones’s parents were ab?
a. 0%.
b. 25%.
c. 50%.
d. 100%.

The correct answer would be a. 0%

Mr. Jones has blood group B and that of their parents was AB. Thus, he must be homozygous for blood group B that is, .

Then, he would only produce one type of gamete, .

The blood group of Mrs. Jones is AB. Thus, the genotype of her gene would be .

Hence, she would produce two types of gametes, one containing and other containing .

The cross would result in the production of children with two types of genotypes and .

Thus, the phenotype of children can be either blood group AB or blood group B.

Hence, the probability of a child having a blood group A would be 0%.

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.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
