Low allozyme and mtDNA variability in the island endemic species Drosophila sechellia (D. melanogaster complex)

Experientia. 1990 Jan 15;46(1):101-4. doi: 10.1007/BF01955430.

Abstract

Genetic variability of D. sechellia is investigated at both mitochondrial and nuclear levels. The results reveal the existence of a single main type of mtDNA with very few variants and a very low enzyme polymorphism. This situation is consistent with the small population size of this specialized species.
