Why do the chromosomes in a homologous pair differ from one another?

Answer 1

They have the same length and gene locus but differ in terms of alleles. An allele is a form of a gene, differing from other alleles of the gene by a few bases at most and occupying the same locus as the other alleles of that gene. The gene locus is the position of a gene on a chromosome. Hope that helped! They have the same length and gene locus but differ in terms of alleles.

Answer 2

They contain diffrenet alelles coding for the same gene .. for example chromosome contains gene coding for eye colour, this gene is found on both chromosomes, but one of them has the alelle for blue colour, and the another has the allele for brown colour ..

Answer 3

Chromosomes in a homologous pair are called homologs because they are similar in size and structure, but they can have different versions of genes, called alleles. Alleles are what give rise to genetic variation within a species. This variation helps to drive evolution by allowing different traits to be passed on to offspring.

Answer 4

Homologous chromosomes are different because the genetic material comes from two different parents. Chromosomes have 23 pairs of genes that come from the parents.

Answer 5

Because of crossing over, chromosomal segments are interchanged between homologous chromosomes
