which of the following genotypes represents a human male?
xy
xo
yy
xx

Explanation:

In humans, biological sex is determined by sex chromosomes. Females typically have two X chromosomes ($XX$). Males have one X and one Y chromosome ($XY$). The $XO$ genotype is associated with Turner syndrome (a female - related disorder in humans). The $YY$ genotype is not a typical human sex - chromosome genotype as humans usually have one X chromosome in their sex - chromosome pair (in addition to the Y in males).

Answer:

XY
