Identification of restriction-fragment-length polymorphisms in genomic DNA of the lesser snow goose (Anser caerulescens caerulescens).

A genomic library of partially EcoRI-digested DNA from the lesser snow goose, Anser caerulescens caerulescens, was constructed in the phage vector Charon 4. Phage containing only unique sequences were identified by screening plaques with 32P-labeled genomic DNA. Restriction-fragment-length polymorphisms (RFLPs) were identified by probing DNA from 11-13 male birds from the breeding colony at La Perouse Bay. Of the 17 probes examined, all detected RFLPs with at least one of EcoRi, HindIII, Msp1, and Taq1. Several of them identified highly variable regions with multiple alleles. These RFLPs are valuable DNA markers that can be used for (1) the examination of DNA variation, relatedness, and genetic distance and (2) assessing paternity and maternity. These data suggest that there are higher levels of variation of DNA sequence in birds than had previously been thought to exist.
