Answer:
pick one
Explanation:
big deal if you have it wrong
A chromosome contains one long DNA molecule.
Each gene in this DNA molecule gives the instructions for making a protein.
Both chromosomes in a pair of homologous chromosomes have the same genes, but the genes in these 2 homologous chromosomes may have different alleles.
Alleles are basically different versions of the given gene.
