<span>Random fertilization adds to the genetic variation thanks to B)Fusion of sperm and ovum, each having a unique combination of chromosomes, introduces further variation. Fertilization is a process of fusion of sperm and ovum. In a random fertilization, it is expected that sperm and ovum each have a unique combination of chromosomes. Thus, the created zygote will have a unique combination of chromosomes which introduces variation.</span>

The answer is A)<span> the desired gene is inserted into the genomes of the pork.
</span>
The techniques of genetic engineering are used to introduce hybrid genes for some desired substance or protein or trait into other organisms. Here, the desired gene is inserted into pork's genome and as a result, it has a <span>higher flesh-to-bone ratio</span><span>.</span>
<span>- B) is not the right answer because it is not necessary to change all the genes in the pork genome or it will be transformed into totally different organism.</span>
<span>- C) is not the right answer because the pork does not have plasmids.</span>
The hereditary form of hypertension is detected when the adrenal gland produces too much aldosterone.
<u>Explanation:</u>
Hypertension is an important risk factor for several cardiovascular disease. If prolonged it damages the blood vessels causing malfunctioning of the heart, kidneys and brain. Hypertension can be caused due to various genetic or environmental factors.
There are cases where familial hypertension are detected. This is caused due to the mutation in a single gene which is passed on to the generations where even in young age the children are seen affected with hypertension.
This in medical terms is termed as familial hyperaldosteronism type II. This is occurred due to the mutation in CLCN2 gene. It tends to produce too much of aldosterone hormone which causes high blood pressure.
