What is a Punnett Square?

Back

A Punnett Square is a diagram used to predict the genetic makeup of offspring from a cross between two parents.

Front

What are the four main blood types in the ABO blood group system?

Back

The four main blood types are A, B, AB, and O.

Front

What is the genotype for blood type A?

Back

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

Front

What is the genotype for blood type B?

Back

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

Front

What is the genotype for blood type AB?

Back

The genotype for blood type AB is IᴬIᴮ.

Front

What is the genotype for blood type O?

Back

The genotype for blood type O is ii.

Front

If one parent is type AB and the other is type O, what are the possible blood types of the offspring?

Back

The possible blood types of the offspring are A and B.

Front

What is the significance of the 'i' allele in blood type inheritance?

Back

The 'i' allele is recessive and codes for blood type O.

Front

How can you determine a parent's genotype based on their child's blood type?

Back

You can determine a parent's genotype by analyzing the child's blood type and using a Punnett Square to see possible combinations.

Front

What is the probability of a child being blood type O if one parent is type A (Iᴬi) and the other is type O (ii)?

Back

The probability of the child being blood type O is 50%.
