What is a XXYY chromosome?
XXYY syndrome is a sex chromosome anomaly in which males have an extra X and Y chromosome. Human cells usually contain two sex chromosomes, one from the mother and one from the father. Usually, females have two X chromosomes (XX) and males have one X and one Y chromosome (XY).
Can XXYY have babies?

What is Turner Klinefelter syndrome?
Turner syndrome (TS) (45X or X0) and Klinefelter syndrome (KS) (47XXY or XXY) are common sex chromosome aneuploidies (SCAs) in humans with an approximate occurrence of 1 in 2,000 female and 1 in 600 male livebirths, respectively (1). TS is due to the partial or complete absence of an X chromosome in females.
What happens when you have XXYY chromosomes?
48,XXYY syndrome results from the presence of an extra copy of both sex chromosomes in each of a male’s cells (48,XXYY). Extra copies of genes on the X chromosome interfere with male sexual development, preventing the testes from functioning normally and reducing the levels of testosterone.
