Generаlly in humаns, mаles are cоnsidered XY and females are cоnsidered XX chrоmosomally. However, SRY is a gene found only on the Y chromosome, which is the actual primary determinant of male characteristics. Therefore, inheriting the SRY gene makes an individual male (XYSRY) and lack of the SRY gene makes an individual female (XX). There is a rare chromosomal disorder in which an individual may be chromosomally XX but would appear phenotypically male by having the SRY gene on the X chromosome (XXSRY). An error during what phase of meiosis would most likely have caused this condition that transferred the SRY gene to the X chromosome? (Hint: The X and Y chromosomes are homologous chromosomes)
