http://www.biology.arizona.edu/human_bio/problem_sets/blood_types/inherited.html WebThe ABO blood group is controlled by a single gene, located on the long arm of the ninth chromosome and thus, as all other autosome-located traits, inherited from both parents. The gene controlling ABO blood group occurs in three alleles: A, B and O. A and B blood groups are dominant over the O group, and co-dominant in relation to each other.

How Blood Groups are Inherited Actforlibraries.org

WebHow are blood groups inherited? Blood types are hereditary. They have a Mendelian pattern, which means that they produce a single gene. The ABO gene has three types of alleles: A, B and O. The first two, A and B, are codominant. That is, they are equally dominant. However, the O allele is recessive. WebLearn about genetic inheritance through blood groups and chromosomes; inherited sex-linked disorders; and human usage of selective breeding and cloning. WebThere are four main blood types: A, AB, B and O. AB positive is considered the universal recipient, and O negative is considered the universal donor.
