They can contain different alleles for the same trait.
Explanation:
The two chromosomes of a homologous pair carry the genes for the same set of traits and these genes are arranged in the same order in both the chromosomes. One chromosome of each homologous pair is contributed by the male gamete and the other by the female gamete.
The organism will be homozygous for a trait, if the two alleles of that trait present on two chromosomes of the homologous pair are same and heterozygous , if these are different.
