An extra chromosome will produce an aneuploidy. It may have severe consequences on the resulting zygote.
<h3>Aneuploidies and chromosome abnormalities</h3>
The term 'chromosome abnormalities' refers to different types of problems that occur in meiosis which are associated with the disjunction of chromosomes.
The most common chromosomal abnormality is called aneuploidy, which means an abnormal number of chromosomes.
Aneuploidy is caused by the presence of an extra or due to the lack (missing) of a chromosome during meiosis.
For example, a trisomy is an aneuploidy due to the presence of an extra chromosome (three copies of the same chromosome instead of two).

The statement 'fish are able to swim faster in a group to avoid being caught by the predator' BEST describes the most likely reason that swimming in a group can help fish avoid a larger predator.
<h3>What is an adaptation?</h3>
An adaptation is an evolutionary strategy to increase the chances of surviving and reproducing in a given environment.
In this case, swimming in a group can minimize friction in the aquatic environment and thus swim faster.
Evolutionary strategies and adaptations may also be individual, but they always have the same objective.
