Homologous chromosomes:
a. carry genetic information that influences the same traits.
b. are genetically identical.
c. are inherited only from the mother.
d. are members of different pairs.

a. carry genetic information that influences the same traits.

Explanation:

Homologous chromosomes are the pairs of chromosomes. One chromosome of a pair is derived from the egg cell while the other comes from sperms. Two chromosomes of a pair carry the gene for the same traits. For example, two copies of chromosome 21 would carry the genes for the same traits in humans. However, these two chromosomes of a homologous pair may have the same or different alleles for a particular gene.

If chromosome 21 carries the gene for eye color in humans, the paternal chromosome may have the allele for blue eyes while the maternal chromosome may carry the allele for the black eyes. However, both of them have the "gene for the same traits (eye color)".
