2. Allele, gene, chromosome

Alleles are alternative forms of a gene for a certain trait.

Genes are regions in the DNA that codes for a proein or an RNA.

Chromosomes are organized structures of DNA and proteins that are found in cells.

Chromosomes are DNA and genes are only segmwens of DNA. Alleles are no structures though the scope of genes are wider than alleles.
