These findings suggest that genes that escape inactivation as well as those within pseudoautosomal regions i.
Nat Genet ; 31 : — This is the same risk for every birth, independent of every other birth. These numbers were too small for further comparisons, but the hetero- vs. Although this last map is based on meioses, its resolution is still limited.

This is the same risk for every birth, independent of every other birth. The twenty-third pair of chromosomes consists of the sex chromosomes. Hidden category: Inserted articles.
These findings suggest that genes that escape inactivation as well as those within pseudoautosomal regions i. Results The results show that parent-of-origin of the X chromosome is reflected in autistic and schizotypal symptomatology.
