Question

12 multiple choice 4 points about how many genes comprise the human genome? 20,000 120,000 3 billion 15,000 13 multiple choice 4 points which of these is not considered to be an \evolutionary force\? sexual selection genetic drift mutations random mating 14 multiple choice 4 points the variety of various living species is niche diversity genetic diversity species diversity ecosystem diversity

Explanation:

• For question 12: Current estimates suggest the human genome has about 20,000 - 25,000 protein - coding genes.
• For question 13: Evolutionary forces include natural selection, genetic drift, mutations, and gene flow. Random mating does not change allele frequencies and is not an evolutionary force.
• For question 14: Species diversity refers to the variety of different species in an area.

Answer:

1. 20,000
2. random mating
3. species diversity
