Answer:
the answer is D. None of the above.
These three factors affect how variations in genotype arise in a population:
<span>1) Sexual recombination- one-half of the parent 1 and one-half of parent 2’s genes are combined to form a brand new gene for the offspring resulting to a new type of combination that is not existing before.
2) Gene crossover- this is the trade-in of genetic material from two cells that each contains a pair or 1 maternal strand and 1 paternal strand of the parents chromosomes (Homologous).
</span>3) Chromosome aberration- it is a mutation in the chromosome wherein there is an extra or missing part of the DNA. <span> </span>
The twenty- first pair of chromosomes failed to seperate during meiosis, so aziz received three of these chromosomes rather than the normal two. Aziz has down syndrome.
It’s definitely C. GoodLuck :)
The domain of the expression is all real numbers except where the expression is undefined.
