Question

Table shows that Turner syndrome occurs when an individual
inherits one X chromosome but lacks a second sex chromosome.
Can Turner syndrome be due to nondisjunction during
oogenesis, spermatogenesis, or both? If a phenotypically normal
couple has a color-blind child (due to a recessive X-linked
allele) with Turner syndrome, did nondisjunction occur during
oogenesis or spermatogenesis in this child’s parents? Explain
your answer.
