The answer should be C, 50%
First we need to find the alleles for Mr Jones. We know that he has a blood type B, so at least one allele should be B, and the other can either be B or O (cannot be A, or else his blood type would be AB because A and B are co-dominant alleles)
Since Mr Jones' parents are both blood type AB, so which means their allels must be A and B, so, we can conclude that Mr Jones alleles should be B and B.
Now we know Mr jones' alleles, we can conduct a punnett square to find the probability. Since Mrs Jones has blood type AB, again, her alleles are also A and B.
From the punnett square attached, we can conclude that their offspring are either blood type AB or pure B. So, the answer should be 50%, C.
Answer:
C. Crossing Over
Explanation:
Crossing over, also called recombination, is the process by which non-sister chromatids of homologous chromosomes exchange a segment of their chromosomal material with one another. The process of crossing over occurs only in the prophase I stage of meiosis.
The process is responsible for genetic variation in the gametes produced, thereby, leading to organisms that are genetically unique.
