#Unit 8. Inheritance Biology
A panel of cell lines was created by human—mouse somatic-cell hybridization. Each line was examined for the presence of human chromosomes and for the production of an enzyme. The following results were obtained:
On the basis of these results, which chromosome has the gene that encodes the enzyme?
