In Sexual progeny there are two sets of chromosome (one from father and one from mother)

Father=44+XY     (Father is a male so his chromosome will be XY)

Mother=44+XX    (Mother is a female so her chromosome will be XX)

Father will produce two set 22+X and 22+Y

Mother will produce two set 22+X and 22+X
