WebIn population genetics, the term evolution is defined as a change in the frequency of an allele in a population.

For example, a study in Jordan found a ... WebYes, mutations can create new genes. Mutations cause changes in the DNA sequence of the gene which can be due to the duplication of large sections of DNA. So, the …

An allele is a variation of the same sequence of nucleotides at the same place on a long DNA molecule, as described in leading textbooks on genetics and evolution.
