<span>Neutral mutations are neither harmful nor beneficial.
Therefore, they are invisible to natural selection. (Since they neither improve nor worsen one individual's chances of survival and reproduction over another.)
However neutral mutations can still spread into the population by just random replications and matings. This is called genetic drift.
In other words, they are 'silent'. They are mutations that exist and propagate in populations, but seem to have no effect at all.
The reason they can become important to evolution is that a day can come when they *do* have an effect. In other words, even though an individual mutation may have no immediate effect on survival or reproduction, a *combination* of neutral mutations may provide some new benefit or harm ... at which point natural selection *will* act on that combination.

If the offspring is a female, it means she got an X chromosome from her mom, and an X chromosome from her father.
Answer:
C.

Answer:
The correct answer is- Preeclampsia
Explanation:
Preeclampsia is a complication during pregnancy which is characterized by high blood pressure in the pregnant woman and damage to internal organs like liver and kidney.
This complication starts normally after 20 weeks of the pregnancy. Before starting preeclampsia the pregnant woman's blood pressure is normal. Preeclampsia can lead to serious complications if it untreated and the delivery of the baby is the most effective treatment.
Therefore preeclampsia is a life-threatening disease, characterized by high blood pressure in pregnant women.
