Question

a species has homologous chromosomes. what does this say about the species?
a. it is a eukaryote and a haploid species.
b. it has dna that is made up of genes.
c. it has alleles that control certain traits.
d. it has pairs of matching chromosomes.

Explanation:

Homologous chromosomes are defined as pairs of chromosomes that have the same gene loci (matching structure and genetic content, one from each parent). Option A is incorrect because haploid species have only one set of chromosomes, no homologous pairs. Options B and C are true for nearly all organisms with DNA, but they do not specifically describe what having homologous chromosomes means. Only option D directly matches the definition of homologous chromosomes.

Answer:

D. It has pairs of matching chromosomes.
