Det är inte lätt att ha en kromosom för mycket.

S.C.U.M. för nybörjare, del 1:

"While taking Biology at the University of Maryland in 1957, Solanas studied human chromosomes (there are 23 pairs). She noticed the male sex chromosomes are XY, and the female are XX. Since the Y chromosome is like the X, but with a part missing, males are more susceptible to deficiencies like baldness, hemophilia, and colorblindness. Solanas determined males are just plain genetically inferior."
