How can mutation change the genetic pool

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.

In both streams, the populations increased 10-fold and genetic diversity doubled. Later generations were more fecund, with many of the most fit offspring being hybrids of the local and introduced fish, Reid reported at the meeting. WebIt should be noted that mutation is the ultimate source of genetic variation in all populations—new alleles, and, therefore, new genetic variations arise through mutation. * Genetic Drift. Another way the frequencies of certain genes can change is genetic drift (Figure 1), which is simply the effect of chance. raygor readability calculator
