One hypothesis was that a separate gene was responsible for each type of chain in the antibody.

Each of these four subunits is encoded by a separate gene.

This is a complex process, requiring 15-20 separate genes.

The white coloring on a calico is from a separate gene unrelated to the orange or black genes.

Each of the steps in heme production is controlled by a separate gene (see below).

Probably four or five separate genes must be knocked out before a normal cell becomes a fully developed tumor cell.

In cattle, this trait has been traced to a separate gene (on a different chromosome) from that responsible for polling.

For instance, Sorghum maturation is controlled by four separate genes.

Each is coded by a separate gene, and some exist in multiple isoforms.

Each is encoded by a separate gene and has different functions, although with some overlap.
