Monohybrid and Dihybrid Practices

Monohybrid Practices

Today, we will practice Monohybrid cross. You will use your knowledge of genetics to solve Punnett squares and predict inheritance patterns. Get ready to apply what you've learned and analyze the probability of different traits appearing in offspring!

Multiple Choice

Which of the following best describes a dominant allele?

• An allele that is always recessive.
• An allele that only expresses in homozygous conditions.
• An allele that has no effect on the phenotype.
• An allele that is expressed even if only one copy is present

Multiple Choice

What is a phenotype?

• The observable physical traits of an organism.

• The environment in which an organism lives.
• The process of natural selection.
• The genetic makeup of an organism.

Multiple Choice

Which genotype represents a homozygous dominant individual?

• AB
• aa
• AA
• Aa

Dihybrid Practices

Today, we will practice Dihybrid cross. You will use your knowledge of genetics to solve Punnett squares and predict inheritance patterns. Get ready to apply what you've learned and analyze the probability of different traits appearing in offspring!

Multiple Choice

If a person has one dominant allele and one recessive allele for a trait, they are considered:

• polygenic
• hemizygous
• homozygous
• heterozygous

Multiple Choice

Identify whether the following is a genotype or phenotype:

Blue eyes

• phenotype
• homozygous

Multiple Choice

Identify whether the following is a genotype or phenotype:

Bb (where B = brown eyes, b = blue eyes)

• genotype
• brown eyes
