Question

Quizplus · Accepted Answer

Karyotyping involves examining a person's chromosomes to analyze their number, size, and shape, and can reveal alterations such as missing or extra chromosomes, which are commonly found in genetic disorders such as Down syndrome. It cannot show points of crossing over or the presence of cancerous genes, and it does not specifically show chromosomes in metaphase of meiosis II.
