Colton blood groups in Canadian Caucasians: frequencies, inheritance and linkage analysis

|January 1, 1977
Abstract:
In a series of 726 random Caucasian adults tested with anti-Coa and anti-Cob allele frequencies were Coa 0.9470, Cob 0.0530. The distribution of Colton phenotypes in 205 children of 57 selected families was in accordance with expectation. A linkage analysis of Co and 26 other loci indicates that Co is not closely linked to AcP1, ABO, AK1, Ch, Do, GLO, Gm, GPT, HLA, Hp, K, Lu, MN, PGM1 or Rh and does not lie between PGD and PGM1 on chromosome 1.

Hardy-Weinberg Principle
Diploid organisms have two alleles of each gene, one from each parent, in their somatic cells. Therefore, each individual contributes two alleles to the gene pool of the population. The gene pool of a population is the sum of every allele of all genes within that population and has some degree of variation. Genetic variation is typically expressed as a relative frequency, which is the percentage of the total population that has a given allele, genotype or phenotype.In the early 20th century,...

Blood Types
Human blood is classified into different types based on the presence of antigens on the red blood cell's surface and antibodies in the plasma. Proper identification of blood type is essential for successful blood transfusion. The International Society of Blood Transfusion has identified 38 human blood types based on the surface antigens on the red blood cells. The most common types are ABO, Rh, and MNS blood types.
