Kamar wants to know his mother's blood type. Kamar knows that his blood type is AB and his father’s blood type is heterozygous A. What can Kamar assume about his mother’s blood type?(1 point)
Responses

Kamar’s mother must be O because the recessive allele allows for Kamar to get type A from his father
Kamar’s mother must be O because the recessive allele allows for Kamar to get type A from his father

Kamar’s mother must be either A or O because blood type AB is considered incomplete dominant.
Kamar’s mother must be either A or O because blood type AB is considered incomplete dominant.

Kamar’s mother must be either AB or B because blood types AB is considered codominant
Kamar’s mother must be either AB or B because blood types AB is considered codominant

Kamar’s mother must be AB because blood type AB is inherited from one parent

Answer 1

Let's go through the questions and their correct responses:

1. In a certain population of rabbits, the ratio of the phenotypes of brown fur and white fur is 1:1. What is the frequency of the white fur trait in the rabbit population?

   • Response: 50%

2. Kamar wants to know his mother's blood type. Kamar knows that his blood type is AB and his father’s blood type is heterozygous A. What can Kamar assume about his mother’s blood type?

   • Response: Kamar’s mother must be either AB or B because blood types AB is considered codominant.

3. Which of the following best describes natural selection?

   • Response: The process by which organisms that are better adapted to the environment tend to survive and produce more offspring.

4. The different variants of a trait available to a gene are called

   • Response: alleles.

5. What is one similarity between genetic drift and gene flow?

   • Response: They both cause a change in the frequency of traits in a population.
