Mitochondrial DNA-Based Analyses of Relatedness Among Turkeys, Meleagris gallopavo.

The domesticated turkey, Meleagris gallopavo, is believed to be a single breed with several varieties whose relatedness and origins remain poorly understood. Using the mitochondrial genome sequence (GenBank accession no. EF153719) that our group first reported, we investigated the relationships among 15 of the most widely occurring turkey varieties using D-loop and 16S RNA sequences.

DNA sequence and haplotype variation in two candidate genes for dilated cardiomyopathy in the turkey Meleagris gallopavo.

Determining variation in genes is fundamental to understanding their function in the disease state. Cardiac troponin T (cTnT) and phospholamban (PLN) genes have been implicated in dilated cardiomyopathy (DCM) in human and model species. To investigate the role of these 2 candidate genes in DCM in the turkey Meleagris gallopavo, understanding sequence variants and map position distribution is necessary.
