a

Paternal transmission of the Y chromosome is limited to male offspring.

b

Paternal transmission of the X chromosome is limited to female offspring.

c

Recombination does occur between the X and Y chromosomes in males but is limited to two small pseudoautosomal regions at the Y-chromosomal telomeres.
