Answer:
A. It allows two populations to evolve separately.
Explanation:
Geographic isolation is theorized to have catalyzed the formation of new species. Let’s say groups A and B of a bird species get separated by something, and they can’t cross between to interbreed or exchange alleles.
We describe this as no gene flow, which is the opposite of choices C and D. Because of this, they may diverge if given enough time due to the difference in environmental pressures, because they’re now in different environments.
B is incorrect because it doesn’t apply.

Answer:
The cells analyzed might be a mosaic of different genomes
Explanation:
The human genome in every cell might not be the same and could give us some misrepresentation of what really happens on our genome. Chromosomal abnormalities are also a very common phenomena to be observed in human cells. For those differences in the genome of the child the test might have identified some altered cells with a type of chromosomal abnormality which was not latter identified or the abnormal cell might be also eliminated by its abnormal nature.
Answer:
Their synthesis is considered to be discontinuous.
Explanation:
Okazaki fragments, which are strands of DNA that are produced seperately and then linked together, this is why their synthesis is considered to be discontinuous.
I hope this answer helps.
