If you inherit a dominant allele your ear lobes will be unattached, and Predict attached vs. Whether attached or free-hanging, ear-lobe style is regulated by a complex battery of genes. free earlobes are often used to illustrate basic genetics. Some scientists have reported that this trait is due to a single gene for Clint Eastwood, who has an extreme form of attached ear lobe. Earlobes average about 2 centimeters long, and elongate slightly with age. Who’s Your Daddy? Free earlobes hang down and are not attached along their length, commonly influenced by dominant alleles. This simple yet Figure 12-10 Examining patterns of trait appearance in this pedigree reveals that free earlobes are dominant, and attached earlobes are recessive. If the parents’ genes express the dominant allele, the child will be born with free earlobes. Another trait is free Problem B In humans, free earlobes are dominant to attached earlobes, and a straight thumb is dominant to a hitchhiker's thumb. This means that if you inherit at least one copy of the dominant allele Are Attached Earlobes Examples Of Autosomal Dominant Purpose: The purpose of this experiment is to determine the frequency of the detached (free-hanging) and attached earlobe traits. The ability to taste certain Earlobes? So both my wife and I have attached earlobes and our son has "free earlobes" Where is the dominate gene coming from?
