• Adaptation

• Allele Frequency

• Genetic Drift

When a small group leaves their mainland to found a new colony, this is considered as

• Bottleneck effect

• Adaptation

• Founder effect

• Cause and effect

A physical trait favored by an environmental change is called an

• Possibility

• Adaptation

• Mutation

• Extinction

When the population significantly decreases due to a natural disaster (meteor, hurricane, etc), this type of Genetic Drift is considered the

• Bottleneck effect

• Gene Flow

• Founder effect

• Allele frequency

What is the correct equation for calculating allele frequency?

• Number of copies of allele of interest / Total number of alleles present

• Total number of alleles present / Number of copies of allele of interest

• Dominant allele / total number of alleles present

• Total number of alleles present / Recessive allele

There are 10 "RR" alleles and 6 "Rr" alleles. What is the total number of alleles present? (1/3)

• 16

• 32

• 4

• 8
