What is false about natural selection?

• It results in stronger individuals

• Heritable

• Differential survival

• Survival of the fittest

What is genetic drift?

• Pre-determined changes in allele frequencies.

• The process in which the better suited individuals adapt.

• Changes in allele frequencies by chance.

• More likely to happen in large populations.

Hardy-Weinberg Equilibrium is represented by which formula:

• p² + 2pq + q²=1

• p³ + 2pq + q²=1

• p³ + 2pq + q³=1

• p² + pq + q²=1

What does the following photo represent (2 words):

Inbreeding causes:

• Increased heterozygosity

• Genetically distantly related

• Decreased homozygosity

• Increased homozygosity

What is meant by heterozygosity?

• Two different versions of the same gene.

• Two identical alleles in a gene
