WebMutations and migrations can affect gene frequencies. Many natural populations are small enough that chance fluctuations can significantly alter gene frequencies. Moreover, in many cases matings may be selective rather than random in regard to certain genetic traits; this will alter the frequencies of genotypes in succeeding generations. WebTypes of genetic mutations include: Germline mutation: A change in a gene that occurs in a parent’s reproductive cells (egg or sperm) that affects the genetic makeup of their child (hereditary). Somatic mutation: A change in a gene that occurs after conception in the developing embryo that may become a baby.
