Question 1
Selection most often acts to eliminate new mutations. This process is called:
◦ genetic drift.
◦ fixation.
◦ genetic hitchhiking.
◦ positive selection.
◦ negative selection.
Question 2
The human genome is estimated to have how many functional, protein-coding genes?
◦ 10,000–12,000 genes
◦ About 20,000 genes
◦ 40,000–45,000 genes
◦ About 80,000 genes
◦ More than 100,000 genes
