A fetus with two Y chromosomes and no X's is not viable. The Y
chromosome has only a few genes that are needed to instruct the embryo
(which starts out female) to become male. Only a few master proteins are
encoded on the Y chromosome.

Here are viable (some are more viable than others) combinations:

XX
XY
XYY
XXY
XXYY
XXXYY
XYYY
XXX
XO
