Chromosomes

Question 6 • First Semester Biology

Which phrases describe homologous chromosomes?

Answer
A
They have the same genes in the same order.
B
One is inherited from one parent, and one is inherited from the other parent.
C
They are the product of copying the chromosomes.
D
They can contain the same or different alleles.

Explanation

Homologous chromosomes have the same genes arranged in the same order, although the versions of those genes (alleles) may be the same or different. In a typical diploid cell, one homolog comes from each parent. Chromosome copying produces sister chromatids, not homologous chromosomes, so C does not describe them.
