Mutation of a Mouse Gene Results in Mice That Lack

Mutation of a mouse gene results in mice that lack heart muscle.What characteristic would you expect to find in a human gene that has a common origin with this mouse gene?

A) The DNA sequence of the human gene will be identical to the DNA sequence of the mouse gene.
B) The human and mouse genes will specify proteins with similar amino acid sequences.
C) The human and mouse genes will specify unrelated sequences of amino acids, but both proteins will function to prevent the formation of heart muscle.
D) The human and mouse genes will specify unrelated sequences of amino acids, and the human gene will not be involved in heart muscle formation.
