What does the variable q represent?

• Frequency of the heterozygote genotype
• Frequency of the homozygous recessive genotype
• The frequency of the recessive allele
• The frequency of the dominant allele 

Which Hardy-Weinberg equation represents the genotype frequencies in a population?

• p + q = 1
• p2 + 2pq + q2 = 1
• p2 + pq2 + q2 = 1
• p + 2pq + q3 = 1
