2. Blood Inheritance

Front

What is a Punnett Square?

Back

A Punnett Square is a diagram used to predict the genetic makeup of offspring from two parents based on their genotypes.

Front

What is the genotype for Type A blood?

Back

The genotype for Type A blood can be either IᴬIᴬ (homozygous) or Iᴬi (heterozygous).

Front

What is the genotype for Type B blood?

Back

The genotype for Type B blood can be either IᴮIᴮ (homozygous) or Iᴮi (heterozygous).

Front

What is the genotype for Type O blood?

Back

The genotype for Type O blood is ii.

Front

What blood types can a homozygous B parent and a type O parent produce?

Back

They can produce type B (Iᴮi) offspring.

Front

Can a child with type AB blood have a type O parent?

Back

No, a child with type AB blood cannot have a type O parent because type O does not carry A or B alleles.

Front

What is the significance of the universal donor blood type?

Back

Type O blood is known as the universal donor because it can be given to any blood type without causing an immune reaction.

Front

What is the significance of the universal recipient blood type?

Back

Type AB blood is known as the universal recipient because individuals with this blood type can receive blood from any other type.

Front

What does heterozygous mean?

Back

Heterozygous refers to having two different alleles for a particular gene, such as Iᴬi for type A blood.

Front

What does homozygous mean?

Back

Homozygous refers to having two identical alleles for a particular gene, such as IᴮIᴮ for type B blood.
