Question

a matched pair of chromosomes are called:
homozygous
homologous
diploid
haploid

Explanation:

Homologous chromosomes are pairs of chromosomes (one from each parent) that have the same length, gene position, and centromere location. They carry genes for the same traits at corresponding loci. Homozygous refers to having two identical alleles for a gene. Diploid means having two sets of chromosomes (2n). Haploid means having one set of chromosomes (n). So, a matched pair of chromosomes is called homologous.

Answer:

homologous
