| Chromosome X has a pseudo-autosomal region (PAR) which can be imputed for males and females together. Imputing the PAR on chromosome X is same as usual imputation, since both males and females are diploids at these sites. However, the non pseudo-autosomal region (non-PAR) needs to be imputed for males and females separately, as males are haploids while females are diploids. Of course, the PAR and non-PAR regions need to be imputed separately. This wiki page gives further details on imputing chromosome X. | | Chromosome X has a pseudo-autosomal region (PAR) which can be imputed for males and females together.
