Larvae have various behaviors (like vertical migrations) that may result in dispersal between adult populatio(cid:374)s o(cid:396) (cid:862)(cid:396)ete(cid:374)tio(cid:374)(cid:863) If the(cid:396)e is dispe(cid:396)sal (cid:271)et(cid:449)ee(cid:374) populatio(cid:374)s, (cid:449)e (cid:272)all the(cid:373) (cid:862)ope(cid:374) populatio(cid:374)s.

Someone looked at tracking the larvae of the coral reef fish population and how far they disperse and if the babies are from the same adult populations. Restricted gene flow (dispersal barriers) can lead to population differentiation due to random mutations and the populations genetically diverge: 2. Natural selection may favor different genotypes in different environments resulting in population differentiation in spite of dispersal.
