An earthquake decimates a ground-squirrel population, killing 98% of the squirrels. The surviving population happens to have bro

ader stripes, on average, than the initial population. If broadness of stripes is genetically determined, what effect has the ground-squirrel population experienced during the earthquake?a. directional selection b. disruptive selection c. a founder event d. bottleneck effect

Answer:

The correct answer is d. bottleneck effect

Explanation:

A bottleneck effect occurs when a large population of a species suddenly decreases in size due to some type of natural disaster like tsunami, earthquake, volcanic eruption, etc. This is a type of extreme genetic drift because in this many allele which was present in the old larger population might lost and the new population has less allele than previous population.

So here 98% of the population died in the earthquake and the remaining population has broader stripes on average than the initial population therefore here the squirrel population experienced bottleneck effect.

Which describes the four cells that are produced at the end of meiosis? identical haploid cells genetically different diploid ce
algol13

Answer:In many ways, meiosis is a lot like mitosis. The cell goes through similar stages and uses similar strategies to organize and separate chromosomes. In meiosis, however, the cell has a more complex task. It still needs to separate sister chromatids (the two halves of a duplicated chromosome), as in mitosis. But it must also separate homologous chromosomes, the similar but nonidentical chromosome pairs an organism receives from its two parents.

Explanation:Mitosis(Opens in a new window)(Opens in a new window) is used for almost all of your body’s cell division needs. It adds new cells during development and replaces old and worn-out cells throughout your life. The goal of mitosis is to produce daughter cells that are genetically identical to their mothers, with not a single chromosome more or less.

Meiosis, on the other hand, is used for just one purpose in the human body: the production of gametes—sex cells, or sperm and eggs. Its goal is to make daughter cells with exactly half as many chromosomes as the starting cell.

To put that another way, meiosis in humans is a division process that takes us from a diploid cell—one with two sets of chromosomes—to haploid cells—ones with a single set of chromosomes. In humans, the haploid cells made in meiosis are sperm and eggs. When a sperm and an egg join in fertilization, the two haploid sets of chromosomes form a complete diploid set: a new genome.
