Two normal parents can have an affected child.
When one parent is affected, about half of their offspring are affected.
Only females transmit the trait to their male offspring.
Affected offspring have only one affected parent.

The parental arrangement of alleles is abC and ABC.
Independent assortment can produce gametes with the genotypes aBC, abC, AbC, ABC.
Crossing-over can produce recombinant gametes with the genotypes abC and ABC.
Crossing-over can produce recombinant gametes with the genotypes aBC and AbC.
The XIST gene is responsible for inactivation.
It occurs randomly early in embryonic development.
It causes heterozygous females to have a mosaic phenotype.
A barr body is typically found in the nuclei of both male and female body cells.
Crossing over does not take place in Prophase.
