Answer:
D
Explanation:
This involves a dihybrid inheritance I.e. two genes are being passed on. During meiosis, specifically, the Prophase stage, homologous chromosomes (similar but non-identical chromosomes received from each parent) line side by side. According to the question, one chromosome contains A and B alleles and its homologue, received by the other parent carries a and b alleles. This means that the diploid individual has a genotype AaBb for that gene.
According to Mendel's law of independent assortment, the alleles separate independently of one another into gametes. I.e. allele A and a separates into the gametes without affecting alleles B and b of the other gene.
Crossing-over, which is the exchange of chromosomal segment occurs between the two homologues. Hence, the exchange of chromosomal segments containing alleles in the individual will possibly produce four gametes with the genotypes: AB, Ab, aB, ab.

There are choices for this question, namely:
<span>chemical name
generic name
brand name
research name

The correct answer is "brand name". The brand name is the name of the drug that is tied to the specific manufacturer. The generic name of the drug is the approved name of the drug which corresponds to its drug class and specific mode of actions. The chemical name, as the name suggests, comprise of the detailed chemical makeup of the drug.
The two most common hypotheses that theorise the formation of life-supporting molecules on earth would be the Miller-Urey experiment and the meteorite phenomenon. In the meteorite theory, it is said that life on earth began when meteorites containing life-supporting molecules bombarded the planet that eventually caused lifeforms to grow.
