It was said earlier that, "Unattached earlobes are the dominant trait, twice as many people have unattached earlobes compared to attached." There is not actually any real proof that unattached earlobes are dominant. While more people may have unattached earlobes, attached earlobes are dominant. This was proved in a pedigree which covered three generations of extended families.
Hairy earlobes are inherited holandricly, which means that it is a sex-linked gene that is only carried on the Y chromosome. If your father has hairy earlobes, you will definitely have hairy earlobes if you're a boy since you can only inherit your Y chromosome from your father. This doesn't necessarily mean that hairy earlobes are dominant. It just simply means that it will always be expressed because is not another Y chromosome to "compete" with it. It would be interesting to know if in those who have XYY syndrome would express hairy earlobes if they inherited a Y with the hairy earlobe gene. If they do, then yes, hairy earlobes are dominant. If not, then hairy earlobes are not dominant.
Attached earlobes are typically considered a recessive trait, meaning that the presence of free earlobes (detached) is dominant.
Attached earlobes is a commonly referred to example of simple genetic dominance. The allele for freely hanging earlobes is dominant, while the allele for attached earlobes is recessive.
Unattached earlobes are dominant while attached are recessive. It is very rare to have both.

An example of a heterozygous recessive genotype is?
An example of a heterozygous recessive genotype is when an individual carries one dominant allele and one recessive allele for a particular trait. One example could be a person with the genotype Aa, where "A" represents the dominant allele and "a" represents the recessive allele.
Are cats curly ears a dominant and recessive trait?
Curling ears in cats can be caused by a genetic mutation that is a dominant trait. When a cat inherits the gene for curled ears from one parent, it will display the trait. Curled ears are not a recessive trait because even when present with a normal ear gene, the curled ear gene will dominate and be expressed in the cat's appearance.
Is free ear lobe trait autosomal or sex linked?
The free ear lobe trait is autosomal. This means that the gene responsible for determining whether someone has attached or free ear lobes is located on one of the non-sex chromosomes (autosomes) and is not linked to the person's gender.
Is the dominant trait free or attached ear lobes?
Attached. During the developing stages of a baby, earlobes can fuse to the head, and this is extremely likely. However, there is an extremely painful infection where the cells that make up the bit of flesh that fuses your earlobes to your head start to die, eventually causing this link to crumble away.
Ear lobes can be either attached or detached the allele for attached earlobes is recessive and the allele for detached earlobes is dominant what must be true if a boy is born with attached your lobes?
He has at least one E allele is correct. I take the quiz
Are rounded ear lobes dominant or recessive?
Whether rounded ear lobes are dominant or recessive depends on the specific genetic variant involved. In general, it is believed that free (unattached) ear lobes are dominant over attached ear lobes. This means that if one parent has free ear lobes and the other parent has attached ear lobes, their offspring are more likely to have free ear lobes.
Is the lop ear in rabbits recessive or dominant?
Yes, the lop ear gene is recessive since it is a mutation.
What ear lobe is the dominant ear lobe attached or dangling?
Dangling earlobe is dominant.
An example of a heterozygous recessive genotype is?

What happens when a person receives on alle for attached earlobes and one for unattached earlobes?
If a person receives one allele for attached earlobes and one allele for unattached earlobes, they will have the trait of attached earlobes since it is dominant over unattached earlobes. The presence of the attached earlobe allele will determine the physical trait of the individual's earlobes.
Is free ear lobe trait autosomal or sex linked?
The free ear lobe trait is autosomal. This means that the gene responsible for determining whether someone has attached or free ear lobes is located on one of the non-sex chromosomes (autosomes) and is not linked to the person's gender.

What are ear titties?
Actually they are not ear tittes they are big ear lobs that grow on your ear either from pearcing your own ears and it got infected or you got it pearced and didnt take care of your ear good enough.........they are caused by wearing fake jewelry or infections.........
Which ear can most people hear best with?
Your dominant foot, eye, and ear should be on the same side as your dominant hand.
Ear lobes can be either attached or detached the allele for attached earlobes is recessive and the allele for detached earlobes is dominant what must be true if a boy is born with attached your lobes?
He has at least one E allele is correct. I take the quiz
What are the Genotypes for free and fixed ear lobes in human beings?
The genotype for free ear lobes is usually represented as FF or Ff, where F stands for the dominant allele for free ear lobes. The genotype for fixed ear lobes is typically represented as ff, where f stands for the recessive allele for fixed ear lobes.
