Which three of the following best describe what would happen if mitosis did not take place?
vaieri [72.5K]

Mitosis refers to the procedure of cell division, in which a cell goes through a carefully mediated nuclear division, which results in the production of two genetically similar daughter cells. The mitosis comprises five active stages, that is, prophase, premetaphase, metaphase, anaphase, and telophase.  

In a single-celled species like an amoeba, it is the process of mitosis by which the cells reproduce. After undergoing through the five stages of mitosis, it is via the procedure called cytokinesis, the single cell dissociates into two similar cells, thus, completing the reproduction.  

During injury, the process of mitosis takes place to substitute the damaged cells. This repair is mainly essential for the blood vessels and skin that safeguards the organs and muscles in the body. Mitosis also assists to substitute the lost blood via a wound.  

Thus, if the process of mitosis would not take place, then the organism would remain a single-cell, asexual reproduction would not take place, and the tissues of the body would not be able to repair themselves.

In a population of rabbits, there are 496 black rabbits and 27 white rabbits. Fur color is determined by a pair of alleles where
Troyanec [42]

Answer:

0.96

Explanation:

It is given that

B is the dominant allele which represents the black color

and b is the recessive allele which represents the white fur.

B being dominant will result into black color fur for genotype "Bb"

Given -

Frequency of black fur allele (p) is 0.8

As per Hardy Weinberg's  first law of equilibrium

p + q = 1\\

Substituting the value of p in above equation, we get -

q = 1-p\\q = 1-0.8\\q= 0.2

q represents the frequency for white fur allele

Frequency of white fur phenotype is

q^2\\= 0.2^2\\= 0.04

Frequency of homozygous black fur phenotype (BB) is

p^2\\= 0.8^2\\= 0.64

As per Hardy Weinberg's second law of equilibrium -

p^2 + q^2 + 2pq = 1\\0.64 + 0.04 + 2pq = 1\\2pq = 1 - 0.68\\2pq = 0.32\\

Combined frequency of homozygous and heterozygous black fur phenotype is

0.64 + 0.32\\= 0.96
