Question

multiple choice question
the two members of a chromosome pair in diploid cells are called

sister chromatids.
daughter chromosomes.
homologous chromosomes.
sex chromosomes.

Explanation:

• Sister chromatids are identical copies formed by DNA replication of a chromosome, joined at the centromere, not the two members of a chromosome pair in diploid cells.
• Daughter chromosomes are the chromosomes after separation during cell division, not the pair in diploid cells.
• Homologous chromosomes are the two members of a chromosome pair in diploid cells, one from each parent, with the same genes (possibly different alleles).
• Sex chromosomes determine the sex of an individual, and not all chromosome pairs in diploid cells are sex chromosomes.

Answer:

C. homologous chromosomes.
