bottleneck. Which of the following statements is most likely to apply to this population?
a.The postbottleneck population exhibits less genetic variation than the prebottleneck population.
b.The bottleneck subjected the population to stabilizing selection.
c.The postbottleneck population has less of a chance of going extinct than did the prebottleneck population.
d.The postbottleneck population exhibits more genetic variation than the prebottleneck population.
e.The postbottleneck population has the same probability of going extinct as did the prebottleneck population.

The post bottleneck population exhibits less genetic variation than the pre bottleneck population.

Answer: Option A

<u>Explanation:</u>

To be precise the bottle neck population is a stage where a particular species undergo dramatic reduction in their population size. It may be due to natural or human activity. Whatever reason might be there are some species that fight to thrive to exist among all odds.  

Hence they undergo certain genetic variation to withstand the declining rate. Low genetic variation is only exhibited in this population so that they do not become a prey for the deleterious effect caused in the environmental changes.

Andrej [43]

Answer:

B. DR, Dr, Rd, dr

Explanation:

This question involves two genes. Alleles D and R are dominant over alleles d and r. These two genes obey the law of independent assortment as proposed by Gregor Mendel.

Based on the question, a genotype RrDd will produce the following combination of gametes following the process of meiosis:

DR, Dr, dR, dr

zavuch27 [327]

Answer:

There is no diagram provided so I will just explain the mitotic cell cycle.

Here’s a quick basic arrangement in chronological order interphase, mitosis, and finally cytokinesis.

So first you start with interphase which consist of three phases G1 phase, S phase, G2 phase. Cellular growth occurs in G1 phase of interphase this is followed by S phase which is simply when DNA replication occurs. Final this is followed by G2 phase or further growth in preparation for mitosis and/or meiosis.  

I am only going to explain mitosis but just so I don’t confuse you meiosis can also follow interphase. So mitosis consist of four phases. Prophase, metaphase, anaphase, and telophase.

Prophase: in this phase the nuclear membrane would dissipate and the chromosomes would condense.

Metaphase: then in metaphase the chromosomes would align in the center of the cell and spindle fibers or microtubules would began growth from the centrioles.  

Anaphase: by the start of this phase spindle fibers would have attached themselves to the chromosomes kinetochores. In this phase the chromatids would separate and that’s really it as you can tell this is the shortest phase in mitosis.

Telophase: finally the chromosomes would be brought to the polar opposite ends of the cell and the nuclear membrane would reform. Also the chromosomes condensed chromosomes would unravel eventually they would be invisible.

Finally the cell would enter cytokinesis were it would split at the cleavage furrow which would have started in anaphase of telophase, all a cleavage furrow is, is microfilaments “pinching the cell” which is just them pulling on either side of the center of the cell.
