Answer:
Mutation plays a vital part in evolution; it is the greatest source of genetic variation. In evolution, it creates a new DNA sequence for a particular gene, creating a new allele. Additionally, recombination can produce a DNA sequence (a new allele) for a specific gene through intragenic recombination.

Mitosis (also known as cellular division) is just copying of cells. So the answer would be 18.If the question were about meiosis (sexual division), then the answer would be 9, because that would make 4 daughter cells, each encompassing half the original number of chromosomes (18).
Answer:
Farmers have been using selective breeding for improving their crop qualities and producing animals with better characteristics.
improved so that mankind can benefit from it.
Selective breeding is not okay on a bigger level where it might eradicate the natural varieties of plants and animals completely. When done on a larger level, the wild-type traits of plants and animals will change and be removed completely. This will lead to lesser genetic diversity.
