<u>Answer:</u>
<em>The exposure of sea bed or undersea surface is called sea-level regression.</em>
<u>Explanation:</u>
Sea-level regression occurs when sea level drops down due to several climatic changes. This triggers extinction of several species. There had been several mass extinctions in the past due to <em>sea-level regression.
</em>
<em>Chances of survival of shallow</em> water species become feeble when the sea level falls. In the case of mass extinctions regression can be seen as a symptom and not a cause.
Marine transgression is the opposite <em>phenomena of regression</em> where sea level rises and covers the land which was previously above the sea level.
The probability of the offspring will be 50%, 50%, and 0% respectively.
<h3>Probability in genetics</h3>
It seems the allele for the trait in question is F(f) from the image.
One parent is heterozygous while the other is homzygous.
Ff x FF
FF FF Ff Ff
Probability of FF = 2/4 or 50%
Probability of Ff = 2/4 or 50%
Probability of ff = 0
