Independent distribution of blood group types and two genetically determined traits in a female population

Certain traits in humans are known to be neutral in nature as they do not influence fitness of the individuals. Traits like ABO blood group, phenylthiocarbamide (PTC) tasting and ear lobe structure are genetically determined and follow Mendelian pattern of inheritance. Genes deciding their expression are situated on separate chromosomes and therefore would be certainly following independent assortment during gametogenesis. Data regarding association of these traits were collected from human female subjects to test whether blood group types show their dependency with other two features. An analysis in this regard clearly indicated that there exist no association between blood group type and PTC tasting and also between blood group and ear lobe structure.
