In cattle, the hornless condition (H) is dominant and the horned condition (h) is recessive. The genetics of human stature has been an area of research and disagreement from some time and, while the exact number of genetic loci involved is not known, the wide variability in human stature appears to be consistent with the combined effects of many dominant/recessive genes. Whether the earlobe is free or attached is a classic example of a simple genetic dominance relationship. You are not required to provide consent as a condition of service. I would posit that the creasing effect is merely a manifestation of the proximity of the lobe to the head itself: in other words the creasing is caused by mechanical phenomena rather than a relationship. Studies show that roughly seventy percent of people in the world have detached earlobes, leaving thirty percent with attached earlobes. ¼ If the first parent is not a carrier and the other is a heterozygous parent the offspring has a ¼ th chance at getting the syndrome, because if one parent is a carrier the child has a 50% chance, added with the fact the other parent is not a carrier increases the chances the child will not get the syndrome.
