What are the possible blood types of the offspring of a cross between individuals?

The genotypes of their offspring could be either IAi or IBi. Their children could be in blood groups A or B, but not AB or O. For more information on blood types inheritance go to our Blood Types Tutorial within the Human Biology Section of The Biology Project.

Who is blood type inherited from?

Blood Inheritance Just like eye or hair color, our blood type is inherited from our parents. Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive. For example, if an O gene is paired with an A gene, the blood type will be A.

What determines what blood type you are?

A person’s blood type is determined largely by genetics, and it does not change through his or her lifetime. A simple blood typing test can be performed literally anywhere by anyone through the use of specially-treated testing cards. One of the main factors that determines blood type is family genetics.

What is the most common blood type?

The most common blood type in the U.S. is O-positive. About 37% of caucasian people, 47% of African Americans, 53% of Latinx Americans, and 39% of Asian Americans have this blood type, according to The Red Cross. Type A-positive comes in second, and B-positive is third most common.

What are the different types of blood type?

There are four main blood types: type A, type B, type AB and type O. Additionally, if a substance called Rh factor appears on the surface of the red blood cells, a person is considered to be Rh+ (positive). Type O+ is the most common blood type, while AB- is the least common.

Why do we have different blood types?

Humans haven’t always had different blood types, but rather evolved to have them over time in response to disease. The reason individual humans have different blood types is that they inherit the trait of their blood having certain antigens on the outside of the blood cells from their parents.
