Question

The haploid number, n, of chromosomes in a human is 23, and the diploid number, 2n, is _____.

A. 23
B. 46
C. 92
D. 69

Anaphase during the first division of meiosis is different from anaphase during mitosis because the __________________ don’t separate.

A. Sister chromatids
B. Homologous chromosomes
C. Centrioles
D. Spindle fibers

Answer 1

The diploid number, 2n, in a human is 46. Anaphase during the first division of meiosis is different from anaphase during mitosis because the homologous chromosomes don't separate.

Step-by-step explanation:

The haploid number of chromosomes in a human is 23. The diploid number is twice the haploid number. So, the diploid number, 2n, in a human is 46 (23 x 2).

During the first division of meiosis, anaphase is different from anaphase during mitosis because the homologous chromosomes don't separate. In anaphase of meiosis I, the homologous chromosomes stay together, while in anaphase of mitosis, the sister chromatids separate.
