Postulate why populations in northern climates have gene pools in which most members have the recessive genotype (bb for blue) for eye color, while populations in Africa and South America more often have gene pools with the dominant genotype (B for brown).

Evolution, consequences, and prevention of antibiotic resistance

How has antibiotic resistance evolved? What are the consequences and what can be done?

Genetic Diversity Among Whooping Cranes

The whooping crane population was down to twenty-one individuals in 1944. Today there are more than 300. What can you speculate about their genetic diversity and what this means to their long-term survival?

Definition of Species

Define species. How important is phenotype in identifying species? Give a specific example. What is the problem for paleontologists in establishing species?
