Nov 18, 2004 · To figure out what blood type the kids of these two parents can have, we can use a genetics tool called a Punnett square. It's really just a chart that helps us organize alleles of genes. We'll put the mom's alleles across the top, and the dad's alleles down the side:

Mar 18, 2022 · In the vast majority of cases, blood type follows a predictable inheritance pattern. Here are a child’s possible blood types for any two parents: Note that the ABO part is in a separate table from the +/- part. These two things are determined by two different genes and are inherited separately. More about ABO blood type:

Nov 17, 2006 · There is one gene that determines the ABO part of blood type. This gene comes in three versions -- A, B, and O. Each of our two copies of this gene can be different versions. So someone can have an A and a B, a B and an O, two A's, etc. Here are the six ways these three gene versions can be combined and what each person's blood type would be:

Sep 14, 2022 · There are four main blood groups (A, B, AB, or O) and a Rhesus (Rh) factor (positive or negative). The blood type is passed down from our parents. The A and B alleles are co-dominant and the O allele is recessive [2]. The ABO gene is located on chromosome 9 and has three alleles, A, B and O [3].

Mar 4, 2022 · The short answer: Both biological parents determine the baby’s blood type. But, you ask: How can a mother with type B blood and a father with type A blood have a child with type A blood? What happened to the B from the mother’s blood? Does this mean the baby only got the father’s blood type? (Short answer: no.)

Feb 8, 2025 · Explore how blood type and genetic markers provide insights into paternity, clarifying common misconceptions and enhancing understanding of inheritance. Determining parentage has evolved with advancements in genetics, offering insights into how blood types can provide clues about family relationships.

Blood groups are determined by genetics. Each person inherits a gene from their parents, one gene from their mother, and one gene from their father - to create a pair. Therefore, the blood groups of parents and children are closely related to each other.

Nov 6, 2024 · To understand which parent determines a child’s blood type, we need to explore how blood type genes are inherited. Each person has two alleles for blood type, one inherited from each parent. These alleles can be A, B, or O, and the combination of these alleles determines the child’s blood type.

Jun 1, 2023 · Meaning that your blood type will correlate with a biological parent’s blood type as they pass down aspects of their heritage to you. If you were to test all the eight billion people alive on the planet, you would find that the most common blood type is O-positive. More than one-third of the United States population has O-positive blood.

Jun 12, 2024 · Our Blood Type Calculator allows you to input the ABO and Rh blood types of the parents to predict the possible blood types of your future child. Blood types are determined by the ABO blood group system and the Rh factor .
