Answer;
-Gametic Isolation
Explanation;
-Gametic isolation is a type of prezygotic barrier where the gametes (egg and sperm) come into contact, but no fertilization takes place.
-In Gametic isolation is when sperm of one species may not be able to fertilize the eggs of another species. For instance, sperm may not be able to survive in the reproductive tract of females of the other species, or biochemical mechanisms may prevent the sperm from penetrating the membrane surrounding the other species' eggs.
Loss of genetic variation.

Answer/Explanation:
<h3>Incomplete dominance</h3>
In incomplete dominance, one allele is not entirely dominant over the other, so heterozygotes (organisms with two different alleles for the gene) show an intermediate or blended phenotype.
For example, consider flower colour.
- If the allele for red flowers (R) was dominant over the allele for white flowers (r), then there are three possible genotypes (RR, Rr, and rr) and two possible phenotypes. (Red (RR and Rr) and white (rr)).
- However, if the allele for red flowers (R) was incompletely dominant over the allele for white flowers (r), then there are three possible genotypes (RR, Rr, rr), and three possible phenotypes (red (RR), white (rr), and pink (Rr))
<h3>Co-dominance</h3>
In incomplete dominance, two alleles are both expressed, one is not dominant over the other. Therefore, heterozygotes (organisms with two different alleles for the gene) express both traits.
For example, consider flower patterns.
- If the allele for spots (F) was dominant over the allele for stripes (f), then there are three possible genotypes (FF, Ff, and ff) and two possible phenotypes. (Spots (Ff and ff) and stripes (ff)).
- However, if the allele for spots (F) was co-dominant to the allele for stripes (f), then there are three possible genotypes (FF, Ff, ff), and three possible phenotypes (spots (FF), stripes (ff), and spots and stripes (Ff))
The correct answer is
Stasis
Population becomes isolated
After rapid change in isolated population
Reintroduction
Life forms that depend on remineralize shells and skeletons will be harmed by ocean chemistry, as would species that are acid-sensitive and organisms higher in the food chain that eat these sensitive animals.
<h3>An organism is what, then?</h3>
An organism is a collection of molecules working together to form an more or less permanent together that demonstrates the characteristics of life. Definitions in dictionaries frequently use general terms like "any biological entity, such as a plant or animal reproduction."
<h3>What two kinds of organisms are there?</h3>
Prokaryotic and eukaryotic organisms are the two primary categories. These type the cells that form the organism are the basis for this differentiation. Prokaryotic cells have a very basic, rudimentary structure without a nucleus. Additionally, membrane-bound organelles are absent.
