Autosomal recessive inheritance of goiter in Dutch goats

The inheritance of congenital goiter due to a thyroglobulin synthesis defect in a strain of Dutch goats has been studied by Mendelian and biochemical methods. Mendelian analysis of 301 matings, resulting in 591 kids, showed an autosomal recessive mode of inheritance. A restriction fragment length polymorphism (RFLP) in the thyroglobulin gene also was used to confirm the recessive mode of inheritance of the defect. In a pedigree consisting of 27 goats, spanning four generations, the genotype determined by RFLP study was in accordance with the observed phenotype and the autosomal inheritance of... Mehr ...
