Amother is unsure who the father is of her newborn. before doing dna analysis, a simple blood test is performed to give some preliminary information. in this case, two men are the potential father so their blood is also collected. here is the summary: mom—o, the baby—b, potential father 1—a, potential father 2—ab. which man is the most likely father? write an explanation to justify your answer.

Potential father 2

The child has one "I^B" allele. The potential father 2 carries "I^B" allele which is absent in the potential father 1.

Explanation:

ABO blood group in human beings is regulated by three alleles. I^A and I^B alleles are codominant over each other and are dominant to the allele "i". The genotype of the mother with blood type "O" is "ii" while that of the baby is "I^Bi". The baby would have received the allele "i" from the mother and the allele "I^B" from the father.

The genotype of the potential father 1 can be "I^AI^A" or "I^Ai" while the genotype of the potential father 2 is "I^AI^B". Since the potential father 1 does not carry allele "I^B", he cannot be the father of the child. On the other hand, the potential father 2 carries one "I^B" allele and therefore, is most likely to have a child with blood type "B" if the mother has the blood type "O"

Father 2 is the answer

Explanation:

This is the answer because father 2 has an AB blood type that can go with the mothers and the baby's

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.

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.
