Answer: The genetic content in non-homologous chromosomes would be different.
Explanation:
Homologous chromosomes have the same length, share the same position of centromere and the same types and location of genes. If two chromosomes of a species are the same length and have similar centromere placements and yet are not homologous, the genetic content would be different.
