What does the variable q represent?

• Frequency of the heterozygote genotype

Which of the following is NOT a condition for Hardy-Weinberg Equilibrium?

• No mutations
• Random Mating
• No natural selection
• No offspring

The Hardy-Weinberg Model is?

• Available at local hobby stores and retailers throughout the Greater Cleveland area.
• A mathematical tool that biologists can use to predict allele frequencies and determine whether or not evolution is occurring within a population.
• Always occurring within populations of organisms in nature.
• Only useful in the lab and cannot be practically applied to real-world populations of organisms.
