The right answer is B- create a bottleneck effect, reducing genetic diversity.
A population bottleneck (also known as a genetic bottleneck) is, in the study of biological evolution, an event corresponding to the fact that a substantial proportion of the population of a species disappears or is prevented from to reproduce.
Population bottlenecks (or bottlenecks) thus reduce genetic diversity, and hence the ability of people to adapt to new environmental constraints such as climate change, or a decline in available resources.
B is the answer. A bottleneck effect occurs when a large, genetically diverse population suddenly experiences some catastrophic even and declines to a very low population.
Codominance is when the two parent phenotypes are expressed together in the offspring. An example is a white flower and a red flower producing offspring with red and white patches.
Telophase is the last stage of cell division. It ends with cytokinesis which is the splitting of the mother cells into two daughter cells. The cell pinches in the equator region with the help of a ring of contractile protein filaments. The formed cleavage furrow grows until the two cells pinch off completely.
Killer whales are found in all oceans. While they are most abundant in colder waters like Antarctica, Norway, and Alaska, they are also found in tropical and subtropical waters. The most well-studied killer whale populations occur in the eastern North Pacific Ocean.
