Genetic parameters of the Chukchi breed populations in generational change
Abstract The purpose of the work is to study the genetic characteristics of reindeer populations in the Chukotka Autonomous Region using DNA microsatellites. Genetic monitoring data for 2013 and 2018 are presented (the interval of one generation). In the genetic parameters of populations statistical...
