Description

The rise and consequences of polyploidy in vertebrates, whose origin was associated with genome duplications, may be best studied in natural diploid and polyploid populations. In a diploid/tetraploid (2 n/4 n) geographic contact zone of Palearctic green toads in northern Kyrgyzstan, we examine 4 ns and triploids (3 n) of unknown genetic composition and origins. Using mitochondrial and nuclear sequence, and nuclear microsatellite markers in 84 individuals, we show that 4n (Bufo pewzowi) are...[Show more]
