Genetic diversity in populations of Gentoo penguins (Pygoscelis papua)
[Free Full Text (pdf)]
RAPD analysis was used to examine the extent of genetic polymorphism in two populations of Gentoo penguin (Pygoscelis papua) from Antarctic Islands (Petermann and Livingston). The chosen three 10 mer oligonucleotide primers accordingly to preliminary results showed different levels of polymorphism in Gentoo penguins at Petermann Island (from 23,53 to 42,86 %) and Livingston Island (from 52,94 to 57,14 %). Nei’s similarity coefficients were in range from 0,5606 (when Gentoo genome profiles were compared with RAPD profiles of two related penguin species: Pygoscelis adeliae (Adelie) and Pygoscelis antarctica (Chinstrep)) to 0,9281 among observed Gentoo penguin populations. Nei’s distances values ranged from 0,0746 to 0,5787 among the populations and species. The obtained results will be used for further estimation of genetic diversity of Gentoo penguins and determination of their taxonomic status.
