Question

an error in gamete formation results in a zygote with an xxy chromosome combination. which characteristic of an individual is affected by this combination?
gender - linked traits
muscle protein structure
cellular respiration
nervous system formation

Explanation:

Gender - linked traits are associated with sex chromosomes. XXY is a sex - chromosome combination. Muscle protein structure, cellular respiration, and nervous system formation are not directly related to the sex - chromosome combination XXY in terms of the most direct characteristic affected. Gender - linked traits are determined by genes on sex chromosomes, and an abnormal sex - chromosome combination like XXY will affect gender - linked traits.

Answer:

gender - linked traits
