Genetics: Inheritance Patterns

Two Andalusian chickens are crossed to produce offspring. One parent has black feathers and the other parent has white feathers. In this type of chicken, feather color is a trait that exhibits incomplete dominance. Which statement is most likely correct about the offspring? All of the chicks will have both black and white feathers. Some chicks will have only black feathers and others will have only gray feathers. All of the chicks will have only black feathers. All of the chicks will have only gray feathers.

All of the chicks will have only gray feathers.

Which statement correctly compares the inheritance of blood type in humans and the inheritance of length of ears in corn plants? - Blood type is controlled by multiple forms of a single gene, while the length of corn ears is controlled by many different genes. - Blood type is controlled by many different genes, while the length of corn ears is controlled by multiple forms of a single gene. - Both blood type and the length of corn ears are controlled by multiple forms of a single gene. - Both blood type and the length of corn ears are controlled by many different genes.

Blood type is controlled by multiple forms of a single gene, while the length of corn ears is controlled by many different genes.

Which statement best describes codominance and incomplete dominance? - In codominance and incomplete dominance, both of the alleles are dominant. - In codominance and incomplete dominance, neither of the alleles are dominant. - In codominance, both of the alleles are dominant; in incomplete dominance, neither of the alleles is dominant. - In codominance, neither of the alleles is dominant; in incomplete dominance, both of the alleles are dominant.

In codominance and incomplete dominance, neither of the alleles are dominant.

Which statement describes the difference between incomplete dominance and codominance? - In codominance, only one allele is expressed in the offspring; In incomplete dominance, both alleles are expressed in the offspring. - In codominance, both allels are expressed in the offspring; In incomplete dominance, only one allele is expressed in the offspring. - In codominance, both alleles are expressed in the offspring; in incomplete dominance, the offspring demonstrate an intermediate form of the alleles from the parents. - In codominance, the offspring demonstrate an intermediate form of the alleles from the parents; in incomplete dominance, both alleles are expressed in the offspring.

In codominance, both alleles are expressed in the offspring; in incomplete dominance, the offspring demonstrate an intermediate form of the alleles from the parents.

Which statement describes the blood type of a person with the alleles IAi? It is type AB because I and i are codominant. It is type AB because A and i are codominant. It is type A because i is dominant and A is recessive. It is type A because A is dominant and i is recessive.

It is type A because A is dominant and i is recessive.

Which statement describes the blood type of a person with the alleles IAIB? - It is type AB because A and B exhibit incomplete dominance. - It is type AB because A and B are codominant. - It is type O because A and B are codominant. - It is type A because A and B exhibit incomplete dominance.

It is type AB because A and B are codominant.

Which statement describes the blood type of a person with the alleles ii? It is type AB because i is recessive. It is type AB because i is codominant. It is type O because i is recessive. It is type O because i is codominant.

It is type O because i is recessive.

___ is an inheritance pattern in which a trait is controlled by many genes.

Polygenic

Which statement best contrasts polygenic inheritance with multiple allele inheritance? - Polygenic inheritance results in offspring with only recessive alleles, while multiple allele inheritance results in offspring with both dominant and recessive alleles. - Multiple allele inheritance results in offspring with only recessive alleles, while polygenic inheritance results in offspring with both dominant and recessive alleles. - Polygenic inheritance is controlled by many genes, while multiple allele inheritance is controlled by three or more different forms of a single gene. - Multiple allele inheritance is controlled by many genes, while polygenic inheritance is controlled by three or more different forms of a single gene.

Polygenic inheritance is controlled by many genes, while multiple allele inheritance is controlled by three or more different forms of a single gene.

Which statements describe codominance? Select three options. Traits are usually dominant. Traits are neither dominant nor recessive. Offspring exhibit an intermediate form of alleles from the parents. Both alleles, one from each parent, are expressed in offspring. Codominance involves the interaction of two alleles.

Traits are neither dominant nor recessive. Both alleles, one from each parent, are expressed in offspring. Codominance involves the interaction of two alleles.

Which statements describe incomplete dominance? Select three options. - Traits are usually dominant. - Traits are neither dominant nor recessive. - Offspring exhibit an intermediate form of alleles from the parents. - Both alleles, one from each parent, are expressed in offspring. - Incomplete dominance involves the interaction of two alleles.

Traits are neither dominant nor recessive. Offspring exhibit an intermediate form of alleles from the parents. Incomplete dominance involves the interaction of two alleles.

(T/F) In the inheritance pattern incomplete dominance offspring demonstrate an intermediate form of alleles from the parents.

True

Two plants are crossed to produce offspring. One parent plant has dark blue flowers, and the other parent plant has white flowers. Flower color in these plants is a codominant trait.
