Question

Write a definition of homologous chromosomes using the terms “gene” and “allele.”

Answer 1

Homologous chromosomes contain the same genes and the same locations, or loci but may have different alleles. But jsut so this definition makes sense, lets define some of the words. 
A gene contains the traits that is passed down from two parents to its offspring. An allele is one part of a pair of genes that are located in a particular spot that controls the same trait.
