Question

Quizplus · Accepted Answer

A normal human male karyotype would have 46 chromosomes (A), which consist of 23 pairs of homologous chromosomes (B). One of these pairs is the sex chromosomes, which are typically one X and one Y chromosome (C). However, the karyotype would not show 46 chromatids (D) because chromatids are the duplicated form of chromosomes that only appear during mitosis or meiosis. Additionally, the karyotype would not show the number of DNA molecules (E) since this is not a characteristic that can be visualized at this level.
