Question

what does a karyotype show?
○ genetic abnormalities
○ relationships among family members
○ carriers of a genetic disorder in a family
○ alleles on each chromosome

Explanation:

A karyotype is an organized display of an individual's chromosomes. It visualizes chromosome number, structure, and size, which allows detection of numerical or structural genetic abnormalities (like an extra chromosome in Down syndrome). It does not show family relationships, identify carriers of genetic disorders (which requires looking at specific gene alleles), or detail individual alleles on chromosomes.

Answer:

genetic abnormalities
