D) karyotypes.

Question

Quizplus · Accepted Answer

Alleles are different versions of the same gene found on a specific location on a chromosome. These different versions can contribute to variations in physical traits or characteristics, which are called phenotypes. Sex chromosomes are a specific set of chromosomes that determine an individual's biological sex (male or female). Karyotypes are the number, size, and shape of an individual's chromosomes, which can be used to diagnose genetic disorders. Therefore, the best choice for the described scenario is A) alleles.
