Livestock genetic origins: Goats buck the trend

Livestock genetic origins: goats buck the trend.

T domestic goat (Capra hircus) often is dismissed as the ‘‘poor man’s cow’’ for its ability to thrive on meager fodder and cope with harsh environments. However, this belies the economic and archaeological importance of the species. From an agricultural standpoint, the world’s 700 million goats provide reliable access to meat, milk, skins, and fiber for small farmers—particularly in developing ...

I-35: Genetic Aberrations in Early Development:The Origins and The Fates

Genetic aberrations are commonly seen in human preimplantation embryos. Non-disjunction and premature division of a chromosome are common in both meiosis and mitosis divisions. The expected result for meiotic aneuploidies is full aneuploidy in the later stages whereas mosaicism is the most frequent event in the cleavage and blastocyst stages. The main causes for mosaicism are post-zygotic event...

The unexpected discovery of Brucella abortus Buck 19 vaccine in goats from 1 Ecuador underlines

27 Very few, mostly old and only preliminary serological studies of brucellosis in goats exist 28 in Ecuador. In order to assess the current epidemiological situation, we performed a cross29 sectional serological study in the goat populations of Carchi (n=160 animals), Pichincha 30 (n=224 animals), and Loja provinces (n=2,024 animals). Only two positive serological 31 results (RB negative and S...

Multiple maternal origins and weak phylogeographic structure in domestic goats.

Domestic animals have played a key role in human history. Despite their importance, however, the origins of most domestic species remain poorly understood. We assessed the phylogenetic history and population structure of domestic goats by sequencing a hypervariable segment (481 bp) of the mtDNA control region from 406 goats representing 88 breeds distributed across the Old World. Phylogeographi...
