That population will have less variability in size which has slower rate of mutation or has experience less mutation.
<h2>What is mutation? </h2>
A mutation refers to a change in a DNA sequence of an organism. Mutations can result from DNA copying mistakes that is made during cell division, exposure to radiation or chemicals which is called mutagens, or infection caused by viruses.
If mutation occurs slowly or not completed, it will leads to less variability in size so we can conclude that the population will have less variability in size has experience less mutation.
having a genetically diverse population make a species more likely to survive a change to the enviroment because random mutations can occur in a species and if a sudden change in the environment were to occur like extreme heat for example, some of the mutations in their DNA may help them survive this extreme heat and the species will be more likely to survive
