Inherited Traits Quiz

What are dominant traits?

• Traits that are expressed when an individual has at least one copy of the dominant allele.

• Traits that are expressed when an individual has at least one copy of the recessive allele.

• Traits that are expressed when an individual has two copies of the dominant allele.

• Traits that are expressed when an individual has no copies of the dominant allele.

What are recessive traits?

• Recessive traits are genetic traits that are only expressed when an individual has two copies of the recessive allele.

• Recessive traits are genetic traits that are only expressed when an individual has one copy of the recessive allele.

• Recessive traits are genetic traits that are always expressed in an individual.

• Recessive traits are genetic traits that are only expressed in males.

What is the role of chromosomes in inheritance?

• Chromosomes are only found in animals, not plants.

• Chromosomes determine the physical traits of an individual.

• Chromosomes contain genes and carry the genetic information from parents to offspring.

• Chromosomes are responsible for the production of hormones.

What is the difference between dominant and recessive traits?

• Dominant traits are expressed when an individual has at least one copy of the dominant allele, while recessive traits are only expressed when an individual has two copies of the recessive allele.

• Dominant traits are more common in the population compared to recessive traits.

• Dominant traits are expressed when an individual has two copies of the dominant allele, while recessive traits are only expressed when an individual has one copy of the recessive allele.

• Dominant traits are inherited from the mother, while recessive traits are inherited from the father.
