Silent blood chimaerism in a mare confirmed by DNA marker analysis of hair bulbs

Abstract

Microsatellite DNA markers in a mare's hair bulbs not concordant with markers in her blood confirmed the hypothesis of chimaerism which had been proposed to explain the apparent parentage exclusion of the mare from her suckling foal. Parentage analysis for this foal based on genetic markers not originating from blood cells of its dam supported a parentage verification conclusion.
