Mitotic anaphase differs from metaphase in possessing

1. same number of chromosomes and same number of chromatids
2. half number of chromosomes and half number of chromatids
3. half number of chromosomes and same number of chromatids
4. same number of chromosomes and half number of chromatids

Correct answer: same number of chromosomes and half number of chromatids

Solution

In mitotic anaphase, sister chromatids separate and each chromatid becomes an independent chromosome, so the chromosome count stays the same. However, the number of chromatids per chromosome is reduced by half because each chromosome now consists of one chromatid.
