Answer: Sex evolved as an extremely efficient mechanism for producing variation, and this had the major advantage of enabling organisms to adapt to changing environments. Sex did, however, come with a cost. In reproducing asexually, no time nor energy needs to be expended in choosing a mate.

Effacement: The cervix – which is normally long and thick, measuring about 1-2 inches, starts to get shorter and thinner. This process is known as effacement. As the cervix gets more and more effaced, it gets shorter and shorter and “pulled up” into the lower part of the uterus.
Dilation: At the same time, the cervix softens and begins to open up – known as dilation. This widening, allows a smooth passage for the baby’s head and the rest of the body from the uterus into the vaginal canal.
Answer:
<u>Polygenic therapies are more likely to show </u><u>unintended effects</u><u> in other regions of the genome likely resulting in harmful diseases.</u>
<u />
Explanation:
Gene therapy involves biotechnological techniques that add or remove gene sequences in the genome. These are typically used in eliminating harmful genes that cause genetic diseases or disorders and are generally thought to improve an individual's quality of life.
Polygenic traits are controlled by several genes. Similarly, polygenic diseases may be caused by variations in several gene sequences. These include hypertension, heart disease, and diabetes. Polygenic therapies are more likely to show unintended effects in other regions of the genome, leading to other deleterious disease-causing effects.
