Short Commentary on: Absence of Genetic Variation in the Coding Sequence of Myostatin Gene (MSTN) in New Zealand Cattle Breeds

The objective of this short commentary is to elaborate on some of the main themes identified in the previously published article entitled “Genetic variation and haplotypic diversity in the myostatin gene of New Zealand cattle breeds”. The absence of genetic variation in the coding sequences of myostatin gene in the New Zealand cattle breeds likely suggests one or more of the effects of selection pressure, cross-breeding and inbreeding and genetic drift.
