WebThere are two commonly used approaches to quantify the distribution of genetic diversity within and between populations. Wright’s F statistics. The decline in heterozygosity due to subdivision within a population has usually been quantified using an index known as Wright’s F statistic, also known as the fixation index.
WebApr 12, 2024 · However, this explanation is likely to be excluded because the genetic diversity of restored populations is comparable with the reference population when the restoration time is ≥50 years, but was significantly lower than the reference populations when the restoration time is <50 years (Figure 3d).
