STUDY FOR GENETIC RELATION BETWEEN THE ATTACHED EAR LOBES AND HAIRY EARS IN A SELECTIVE IRAQI SAMPLE

In most people the ear lobes hang free (unattached). This is the dominant trait (E). the attached earlobe is recessive (e). In this study a selective Iraqi sample (66) were examined for attached or free ear lobe, hairy ear and short fingers. The results showed a very strong relation between attached ear lobe and the other two characters, P value equals 0.00 in both. Also the relation between hairy ear and short fingers characters was very strong, P value equals 0.00. Experimental work showed that all men who have attached ear lobe and hairy ear have translocation in chromosome number 22
