What characteristics do two homologous chromosomes share?

• D. They are always inherited from the same parent.

Answer: (B)

Verified step by step guidance

1. Understand that homologous chromosomes are pairs of chromosomes in a diploid organism, one inherited from each parent.
2. Recognize that homologous chromosomes have the same genes at the same loci, meaning they have the same position on the chromosome for each gene.
3. Note that while homologous chromosomes have the same genes, they may have different alleles, which are variations of a gene.
4. Clarify that homologous chromosomes are not identical in DNA sequence because they can have different alleles.
5. Remember that homologous chromosomes are not connected by a centromere; each chromosome in the pair has its own centromere.
