3.5 Estimation of inbreeding level
A total of 78 ROHs were detected, with almost all of them (76) found in
25 invasive diploid individuals from the LL population (Figure 6 and
Table S1). The number of ROHs per individual ranged from one to eight
(mean: 3.04), and the total length ranged from 0.518 to 5.989 Mb (mean:
2.129 Mb). The genomic inbreeding coefficient
(F ROH) was low, ranging from 0.0003 to 0.0038
across individuals, with an average value of 0.0014. The ROHs of a
length from 0.518 to 5.989 Mb suggested inbreeding events that have
occurred 3-39 generations ago.
