Webpatterns of genetic structure within a 472-ha population of 185 individuals to infer pro- ... Despite high levels of gene flow (standard deviation of gene dispersal = 360 m), marked patterns of isolation by distance were detected, associ-ated with an aggregated distribution of individuals in ... Web2 days ago · Here, we show that although there continues to be gene flow between populations of maize weevil, that fine-scale genetic structure exists. It is possible that this structure is shaped by local adaptation of the insects, the movement and trade of maize by humans in the region, geographic barriers to gene flow, or a combination of these factors.

WebAug 15, 2024 · The effect of dispersal ability on genetic structure has been demonstrated in some soil animals. The limited dispersal ability of soil annelids (such as earthworms) hinders the gene exchange between their populations. ... Bohonak, A.J. Dispersal, gene flow, and population structure. Q. Rev.

Yoshimatsu and co-workers (1993) proved that L. affinis would take at least 3 months to reach a total length of 60 mm, and the prolonged pelagic larval duration would improve the dispersal ability and enhance gene flow greatly. food luck 食运
