Brachydactyly is a genetic condition in which the fingers are abnormally short in heterozygotes. Brachydactyly is caused by a recessive allele and the homozygous recessive condition is lethal during pregnancy. Which of the following fractions of live progeny would you see in the mating between two individuals with Brachydactyly? (Read this question carefully). OA. ¼ affected and ¾ unaffected O B. 1/3 affected and 2/3 unaffected ½ affected and ¼ unaffected OD. 2/3 affected and 1/3 unaffected O . All unaffected
