explain how two family members can have different inherited traits.

They can be affected by more than one gene, more than two alleles, or factors other than genetics. Have a good day =D

Two family members can have different inherited traits possibly from evolution.

A drug used to treat CML, imatinib, binds to the active site of Abl kinase. Why does this drug work to treat this type of cancer?

B) By binding to the active site, the drug prevents the ability of Abl kinase to bind to its substrate.

Imatinib works against CML by binding close to the ATP binding site of bcr-abl. The binding results to the locking in of the bcr-abl to a closed or self-inhibited conformation and inhibiting the enzyme activity of the protein semi-competitively.
