What are the possible blood types for humans?
What are the possible combinations for a human with the blood type A?
What are the possible combinations for a human with the blood type B?
Blood type AB is always heterozygous.
For a human to have blood type O, they must be homozygous recessive.
Mrs. Weasley has Type A blood but she is not sure if she is homozygous or heterozygous. Mr. Weasley is completely unsure of his blood type.
Their children have the following blood types: Percy has Type AB blood, Fred & George have Type A blood, Ron has Type O blood and Ginny has Type B blood.

What percent of the offspring do you expect will have...
Type A blood
Type B blood
Type AB blood
Type O blood
A father is heterozygous for Type A blood and the mother is heterozygous for Type B blood.
What percent of the offspring do you expect will have...
Type A blood
Type B blood
Type AB blood
Type O blood
In 1968, a couple accused a hospital of switching their baby with another. DNA fingerprinting did not exist at this time so the hospital traced the blood types of the family in order to determine if a mistake was made. The mother has Type A blood, the father has Type AB blood, and the baby has Type O blood.
Did the hospital make a mistake and switch the baby?
If a child has Type A blood and his mother is heterozygous for Type B, what are the possible genotypes of the father?
Brenda claims that Jose is not the father of her child. Brenda has Type A blood and Jose has Type B blood. The baby has Type O blood.
What do you think?
Two men claim that they are the father of one little boy. A blood test was done to see if either one of the men could POSSIBLY be the father. The first man, Dwight, has Type A blood. The second man, Robert, has Type O blood. The little boy has Type AB blood and the mother, Angela, also has Type AB blood.
Who is the father of the little boy?
A model of the eye color in fruit flies is shown below.
A Red eyed fruit fly (Rrs) is crossed with a Brown eyed fruit fly (rbrs) shown in the cross bellow.
Based on the results of the cross above the expected phenotypic ratios can be:
red : brown : sepia : white
In cats, coat color is codominant AND it is an X-linked trait. Meaning coat color is ONLY carried in the X chromosome.
Possible genotypes and phenotypes for females and males are shown in the table below.
Which table shows the expected phenotypes of offsprings resulting from a cross between a Female Calico cat and a Male Orange cat?
What is the genotype of the father?
What is the genotype of the mother?
What are the possible blood types of babies born from this couple?
