Homework Answers
Homologous chromosomes are reffered to a pair of chromosomes which have same gene at each loci but may have different alleles. They might or they might not have exact same allele at each other. They are assigned the same chromosome number. The size of homologous chromosome is usually the same.
So the false statement is E.
