As a result of nondisjunction,an individual with Turner syndrome is genotypically XO,lacking one of the sex-determining chromosomes.Taking this into account,the fusion of the gamete containing the extra chromosome with a normal gamete could result in an individual with the genotype

- If the gamete with the extra X chromosome fuses with a normal X-containing gamete, the resulting genotype would be XXX (trisomy X). This is option A.
- If the gamete with the extra X chromosome fuses with a normal Y-containing gamete, the resulting genotype would be XXY (Klinefelter syndrome). This is option B.
- It is not possible to get XYY genotype through nondisjunction in females because such an individual would have to inherit a Y chromosome from one of their parents.
- Option E is not correct, because option D already includes all the possible results of nondisjunction in Turner syndrome.
