A person with three complete sets of chromosomes would have which condition?

• A. Mutation
• B. Polyploidy
• C. Genome
• D. Karyotype

Answer: (B)

Having three complete sets of chromosomes is polyploidy, a state in which the organism has more than two full sets of chromosomes (3n in this case). This means the genome contains an extra complete copy of every chromosome, not just a single gene altered. A mutation, by contrast, is typically a change in one gene or a small region of DNA, so it doesn’t describe the number of chromosome sets. The genome term refers to the full content of genetic material, not how many complete copies of each chromosome are present. A karyotype is the visual profile of chromosome number and structure; it can reveal extra chromosome sets, but it’s describing what’s observed rather than naming the condition itself. Polyploidy encompasses triploidy here and is a distinct chromosomal state from the other terms.
