Answer #1

Thos is a pedigree of Autosomal recessive disorder. If the dominant and recessive allele are 'A' and 'a' respectively then the genotypes of all the individuals are :

ཤ༠ གཤ, ༤ ཀྱི་ ༡༡ aa AA/ A ཤིག །—་ཀཾ་ 4A // AA/༢༢ [༢]

The individual no. 12 may have genotype Aa(Carrier) or AA(Not affected).

So the probability of individual 12 being a carrier is 1/2 ihat is 0.5
