Answer:</h2>
To obtain more amount of single cell, a method called <u>cell culture</u> is employed.
<h2>
Explanation:</h2>
Cell culture, otherwise called limited cells, will be cells that are legitimately arranged from a life form's tissues. Whenever placed under the correct conditions essential cells will develop and multiply, however they are just ready to do so a limited number of times. As far as possible is identified with the telomere length toward the finish of the cell's DNA.
As cells experience every cell division, a little portion of the telomere is lost after each time DNA is copied. This procedure in the long run prompts a phase of senescence, where the cells can never again separate. Persistent cell lines, then again, can get away from the ordinary limitations of the cell cycle and develop inconclusively, making them incredibly helpful for long haul inquires about.
A non-disjunction in meiotic anaphase occurring in either an egg or sperm might produce a human zygote with 45 chromosomes. A condition in which human contain 45 chromosomes instead of 46 chromosomes is called aneuploidy or abnormal chromosome number.
<h3>What is aneuploidy?</h3>
The occurrence of one or more extra or missing chromosomes leading to an unbalanced chromosome complement, or any chromosome number that is not an exact multiple of the haploid number (23). It is the presence of an abnormal number of chromosomes in a cell, for example a human cell having 45 or 47 chromosomes instead of the usual 46. An extra or missing chromosome is a common cause of some genetic disorders. The most common cause of aneuploidy happens during cell division when the chromosomes do not separate properly between the two cells.

I think it lived about 50 million years ago because I know for sure it has to be greater than 10,000 because that is the minimum. It states that fossils are dated more than 10,000 years. Don’t take my word yet, wait for other replies,I could be wrong

Answer:
Hazel - 1/4 or 25%
Green - 1/2 or 50%
Blue - 1/4 or 25%
Explanation:
First, let us carry out the cross between AaBB and Aabb using a Punnet's square. The result is as below:
AABb - 4/16
AaBb - 8/16
aaBb - 4/16
(See the Punnet's square analysis in the attached image).
<em>AABb genotype has 3 pigments, hence, would be hazel.</em>
<em>AaBb genotype has 2 pigments, hence, would be green.</em>
<em>aaBb has one pigment, hence, would be blue.</em>
Expected progeny:
<em>Hazel - 1/4 or 25%</em>
<em>Green - 1/2 or 50%</em>
<em>Blue - 1/4 or 25%</em>
