• Individuals with antenna are heterozygous

• Individuals without antenna is heterozygous

Consider that A is Antenna and a is no antenna.

Which statement is true?

• The frequency of A is 6/22

• The frequency of A is 6/28

• The frequency of a is 16/22

• The frequency of a is 16/28

Which statement about the bottle neck effect is true?

• It doesn't change the allele frequencies of a population.

• It only changes one allele frequency in the population.

• The population can always regrow to the original size.

• All allele frequencies can change after a bottle neck event.

Does a bottle neck event act on or against individuals with certain traits?

• No- it is random on which individuals survive.

• No- it only affects the survivors.

• Yes- it acts on weak individuals.

• Yes- individuals only survive if they hide.

What changes did this bottle neck event have on the population?

• The result was a greater frequency of RED individuals.

• The result was a greater frequency of ALL individuals.

• The result was a loss of RED individuals.

• There was no change in allele frequencies.
