How is hemophilia inherited?

• It is inherited in an X-linked recessive pattern.

• It is inherited in an autosomal dominant pattern.

• It is inherited through environmental factors.

• It is inherited in a Y-linked pattern.

What is the role of carriers in genetic inheritance?

• Carriers are individuals who have two copies of a dominant allele.

• Carriers are individuals who have one copy of a recessive allele that does not manifest in their phenotype but can be passed to offspring.

• Carriers are individuals who express the recessive trait in their phenotype.

• Carriers are individuals who have no genetic contribution to their offspring.

What does a vertical line connecting parents to offspring indicate in a pedigree?

• It indicates the parents' marriage.

• It indicates the offspring of those parents.

• It indicates a genetic mutation.

• It indicates a divorce between the parents.

How can you identify a carrier for hemophilia in a pedigree?

• A carrier for hemophilia is represented as a fully shaded circle (female) or square (male) in a pedigree.

• A carrier for hemophilia may be represented as a half-shaded circle (female) or square (male) in a pedigree.

• A carrier for hemophilia is represented as an unshaded circle (female) or square (male) in a pedigree.

• To determine the exact genetic makeup of an individual.

• To create new genetic variations through selective breeding.

• To identify all possible genetic disorders in a population.
