WebA. Mutations can spontaneously occur during DNA replication. Sometimes, during the process of replication, the DNA code is copied incorrectly, and an incorrect nucleotide is attached to the new strand of DNA. This incorrect copy is known as a B. mutation. Genes can sometimes be exchanged between homologous chromosome pairs.

WebMar 25, 2024 · A gene variant is a permanent change in the DNA sequence that makes up a gene. This type of genetic change used to be known as a gene mutation, but because changes in DNA do not always cause disease, it is thought that gene variant is a more accurate term. Variants can affect one or more DNA building blocks (nucleotides) in a gene. WebWhen a phenotype produced by certain alleles helps organisms survive and reproduce better than their peers, natural selection can increase the frequency of the helpful alleles from one generation to the next – that is, it can cause microevolution.

WebMutation is a change in the DNA sequence of the gene. A mutation can change one allele into another, but the net effect is a change in frequency. The change in frequency resulting from mutation is small, so its effect on evolution is small unless it interacts with one of the other factors, such as selection.
