In pedigree analysis, the parents had no clinical sign, the affected dams had clinically normal calves, and approximately equal numbers of males and females were affected, we therefore considered this syndrome to be an autosomal recessive trait. Quantitative genetic analyses were then made in a restricted area. Segregation analysis by the a priori method in 8 families showed that C-HS was a simple autosomal recessive trait. Furthermore, 36 dams and their 257 offspring (including 8 C-HS affected cattle) were analyzed using population genetics in the same area. The result was the same as in the former analysis.}, pages = {501--504}, title = {Inheritance of Chediak-Higashi Syndrome in Japanese Black Cattle}, volume = {58}, year = {1996}, yomi = {タカハシ, ヨシヒロ and カセダ, ユウジロウ and ウチダ, カズユキ and ヤマグチ, リョウジ and スズキ, カツシ and オガワ, ヒロユキ and オオツカ, ヒロミツ} }
