In the 1950s, an average chicken used for their meat—known in the industry as a "broiler" chicken—weighed about two pounds at 56 days old. Today, after decades of selective breeding, an individual bird of the same breed and age weighs in at more than nine pounds.Introduction. T wo phenomena of increasing importance in zebrafish husbandry are inbreeding depression and its antithesis, outbreeding enhancement or hybrid vigor. Inbreeding depression is observed in many species as the loss of fitness in a population from increasing homozygosity. 1 It can be caused by a general loss of heterozygosity in a population or by the unmasking of deleterious alleles ...
