Question

what is the genotype (genetic combination of alleles) of a woman who is a carrier of the disease (Heterozygous)?

Answer 1

Carriers are the person , who donot exhibit the disease but carries or passes on the disease to next generation. Mostly their genotype is hetrozygous . For a female carrier thier genotype would be [X(H) X(h)]. Where H is the normal functioning gene and h is the gene responsible for disease manifestation.

Normally for carrier females there will not be any disease manifestations , if they marry males with normal genotype [X(H)Y], in the offsprings 50% females are carriers and 50 % male have disease manifestations.  

If the carrier female marries affected male [X(h)Y] , 50% females are carriers other 50% females have disease manifestations. 50 % males have disease manifestations and 50% are normal .
