A gene family has been identified that has undergone extensive duplication in humans but is present in only one or a few copies in other primates or other mammals. What experimental approaches could be used to determine the function of this gene and its significance in human evolution?
Reduce the number of copies of this gene in a human subject.
Determine the timing and location of expression of these genes during embryonic development in fruit flies.
Introduce these genes into yeast and study the phenotype of the resulting cells.
All of the listed responses are correct.
Create knockout mice to determine their phenotype.
