Hardy-Weinberg Check

Crossing over occurs in which phase of meiosis?

• Metaphase 1
• Metaphase 2
• Prophase 1
• Prophase 2

In the Hardy-Weinberg Equation, q² is the frequency of what?

• The recessive allele 
• the dominant allele
• the recessive genotype
• the dominant genotype

X-linked recessive disorders are more likely to affect which gender?

• Males 
• Females
• Both Equally
• No one can have the disorder

What percentage of the offspring are homozygous recessive when you cross two heterozygotes for a trait? 

• 25%
• 50%
• 75%
• 100%

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 is a mechanism for change in allele frequency?
