Inherited Traits

What is the likelihood of a child having black hair if both parents have black hair?

• 50%

• 25%

• 75%

• 100%

If a child has blue eyes, what eye color genes must they have inherited from their parents?

• Three blue eye color genes

• Two green eye color genes

• Two blue eye color genes

• One blue eye color gene

If a person with blood type AB has a child with blood type O, what are the possible blood types of the child's other parent?

• O

• AB

• ABO

• A or B

Which physical trait is most commonly inherited from parents?

• Acquired traits

• Education

• Genetics

• Environment

How is hair color inheritance different from eye color inheritance?

• Hair color inheritance is determined by a single gene, while eye color inheritance involves multiple genes.

• Hair color inheritance follows a Mendelian inheritance pattern, similar to eye color inheritance.

• Hair color inheritance is solely influenced by environmental factors, unlike eye color inheritance.

• Hair color inheritance involves multiple genes with varying dominance levels, leading to a wider range of colors. Eye color inheritance is primarily controlled by one or two genes with clear dominant-recessive relationships, resulting in fewer color variations.

Can two parents with brown eyes have a child with blue eyes? Why or why not?

• No, it is not possible for two parents with brown eyes to have a child with blue eyes.

• Yes, if one parent has a recessive blue eye gene.

• No, eye color is not determined by genetics.

• Yes, it is possible for two parents with brown eyes to have a child with blue eyes.

What are the possible blood type combinations for children if one parent has blood type A and the other parent has blood type B?

• A, B, B, O

• A, B, AB, O

• A, O, AB, B

• A, A, AB, B

What physical traits can be inherited from grandparents?

• Blood type, fingerprints, intelligence

• Personality traits, allergies, shoe size

• Hair color, eye color, height, facial features, and certain health conditions

Explain the concept of dominant and recessive traits in inheritance.

• Dominant traits are only expressed when an individual has two copies of the dominant allele.

• Dominant traits are always more common in a population than 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.

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

How do inherited traits play a role in genetic diversity within a population?

• Inherited traits have no impact on genetic diversity

• Genetic diversity is solely determined by environmental factors

• Inherited traits contribute to genetic diversity by passing down variations in genes from parents to offspring, leading to a wider range of traits within a population.

• Inherited traits always result in identical offspring
