Because genes must be able to adapt to either the internal or exterior environment, they are regulated. Since DNA duplication begins with transcription, there are benefits to controlling transcription precisely.
The process of activating and deactivating genes is referred to as gene regulation. During development, genes are turned on and off in various patterns to give a brain cell a different appearance and behaviour from a liver cell or a muscle cell. There are two types of control . Limiting the amount of mRNA that can be created from a single gene is one way to control transcription. Another way is through post-transcriptional processes that affect how mRNA is translated into proteins.

Answer:
Selectivity in choosing a mates
Geographic barriers separating subpopulations.
Explanation:
Selectivity in choosing a mates is a factor in which individuals can mate with each other. Some individuals tend to choose a sexual mates that posses some traits or characteristics that attract them to each other and because of the observable character, similar individuals attracted to each other mates.
Geographic barriers separating subpopulations is another factor that make similar organism or individuals to mates.

They tend to mate with each other in the same geographic location and cannot mate with other subpopulations that is outside their own geographic location. These is common in animals.
