Abstract

LIMA-ROSA, Carlos André da Veiga et al. LEI0258 microsatellite variability and its relationship to B-F haplotypes in Brazilian (blue-egg Caipira) chickens. Genet. Mol. Biol. [online]. 2005, vol.28, n.3, pp. 386-389. ISSN 1415-4757.  http://dx.doi.org/10.1590/S1415-47572005000300008.

A total of 149 chickens from two different sources (one non-commercial, the other commercial) was tested for variability of the LEI0258 microsatellite. Fifty- three genotypes, explainable by 15 alleles, were found. There are clear allele and heterozygosity differences between the two samples. One of them was simultaneously studied for the MHC B-F haplotypes. Strong genetic disequilibrium was observed between the variants of the two systems, therefore providing a cheap alternative for MHC genotyping.
