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.

A population of 150 individuals has an allele frequency of 0.3 for the dominant allele (B) and a frequency of 0.7 for the recessive allele (b). Use the Hardy-Weinberg equation to determine freq.(Bb).

• 0.09
• 0.42
• 0.49
• 0.21

A population of 150 individuals has an allele frequency of 0.3 for the dominant allele (B) and a frequency of 0.7 for the recessive allele (b). Use the Hardy-Weinberg equation to determine freq.(bb).

• 0.09
• 0.42
• 0.49
• 0.21

If the frequencies are as follows in a population with a total size of 150: f(BB)=0.16, f(Bb)=0.48, and f(bb)=0.36, determine the expected numbers of organisms with genotype bb.
