_______________ is a change in the traits of a population over time. Traits are characteristics like looks or behaviors.

What happened to the horse as it evolved?

• It became bigger

• It became smaller

Describe the allele frequency change in this image.

• Evolution did not occur because there was no allele frequency change.

• Evolution did occur because there was an allele frequency change to have more of allele B over time.

• Evolution did occur because there was an allele frequency change to have more of allele A over time.

If allele B made bacteria resistant to antibiotics, which of the following is correct:  

• The bacteria population is more likely to be killed by antibiotics

• The bacteria population will always be killed by antibiotics

• The bacteria population is less likely to be killed by antibiotics

In this population of 10 bacteria, what is the allele frequency of the red, A allele?

• 100%

• 70%

• 30%

• 0%

Two copies of each gene

• Diploid

• Haploid

2 copies of the same allele

• Heterozygous

• Homozygous
