Briefly explain why only chromosomes of a homologous pair can have their alleles referred toas homozygous or heterozygous
tatuchka [14]

This is due to the fact that only homologous chromosomes would have identical genes located at identical sites on those chromosomes. Otherwise, there would be no connection between the alleles of various genes.

Although the genes and loci of the two members of the homologous pair are similar, the alleles may vary.For instance, both allele possess the genes responsible for the attribute of eye colour. While the one has alleles for the blue-eye trait, other has alleles for the brown-eye trait. The homologous chromosomes are said to be heterozygous in this instance since the alleles are different.

On the other hand, when both alleles for a gene that codes for the blue-eye phenotype are present, it is said to be homozygous.
