Answer:
in a certain population of red squirrele, a mutation causes several squirrels to
be bom with darker coats. These coats make the squirrels nearly inweible
when they are foraging on the forest floor
, According to the theory of evolution by natural selection, what is likely to happen to this trait after several generations?
After several generations, this trait is likely to be much more common because individuals with the trait will have a greater chance of passing it on to their offspring,
Explanation:
It would later turn to what is termed as germline mutation which are mutations passed from parent to offspring, as time progresses the trait would be more and increases the chance of being transferred to their offspring

The correct answer is:
The principal cause of aneuploidy is chromosome nondisjunction during mitosis or meiosis. Polyploidy in nature can result either from the duplication of euploid chromosome sets from a single species or from the combining of chromosome sets from different species.
Aneuploidy is a phenomenon when there is the presence of an abnormal number of chromosomes in a cell (an extra or missing chromosome). Usually it appears as a result of improper cell division (chromosomes don’t separate) and it can cause many genetic disorders.
Polyploidy refers to a state when there are more than two sets of chromosomes (one from mother one from father). Triploid (three sets of chromosomes) and tetraploid (four sets of chromosomes) chromosomes are examples of polyploidy. This phenomenon is most common in plants.
