This is called co-dominance. It is when neither alleles are dominant or recessive. Therefore, both traits are expressed.
Ex. Some horses have two hair colors. For example, if two hairs are next to each other, one hair would be red, and the other would be brown.
I am taking a class on this and free/attached earlobes are not co-dominant, its a recessive/dominant trait. I also have one free and one attached earlobe and am not sure how it happens, all i know is that free earlobes are dominant and attached are recessive.

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.
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.
What is the phenotype of a man who has 2 parents with free hanging earlobes if one parent is homozygous and the other parent is heteroygous... what are his possible genotypes?
The man could have either free hanging or attached earlobes. His possible genotypes could be either homozygous for free hanging earlobes (LL) or heterozygous for free hanging and attached earlobes (Ll).
Is unattached earlobes autosomal?
Yes, the trait for unattached earlobes is autosomal. This means that the gene responsible for determining earlobe attachment is located on one of the non-sex chromosomes.
If you know that the allele for attached earlobes is recessive and a friend of yours has attached earlobes what do you know about your friends the mothers and the fathers genotype?
If your friend has attached earlobes (recessive trait), then your friend must have two copies of the recessive allele for attached earlobes (aa). This means that both of your friend's parents must be carriers of the recessive allele (Aa) in order to pass it on. Your friend's mother and father would both have one dominant allele (A) for free-hanging earlobes and one recessive allele (a) for attached earlobes.
What is a free earlobe?
A free earlobe is one that hangs down and is not connected to the side of the head by any tissue, giving it a dangling appearance. It is the most common type of earlobe shape.
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 the smallest bone located in your earlobe?
No, the earlobe is just a fleshy skin tag. For some people it is attached and small. The smallest bone is the stapes or stirrup. It is one of the three auditory ossicles of the middle ear and it enters the cochlea of the inner ear.
If both of the parents have attached earlobes what is their genotype?
The phenotypes of attached and unattached earlobes do not fit neatly into the Mendelian theory of two alleles for one trait, and there is a continuum of earlobe phenotypes. That said, unattached earlobes are a dominant trait, so if the individual is homozygous for unattached earlobes, all of her offspring will have the unattached phenotype, even if some or all of them are heterozygous.
When cutting hair should you use your temples as a guide to cut the top?
That's one way of doing it. Another is to image a line going from earlobe to earlobe
What is the probability of having a child with attached earlobes when an individual with attached earlobes mates with an individual heterozygous for free earlobes?
Attached earlobes are a recessive trait. When one parent has attached earlobes and the other is heterozygous for free earlobes, the chances of any particular offspring having attached earlobes is fifty percent.
Where do you get a free Justin Bieber shirt?
That is highly not going to happen. You have to buy one, they are not free.
Can an allergic reaction cause one earlobe redness?
Yes. They don't have to be on both sides of the head.
If you go to Bulgaria would you get a tour?
No FREE meal anywhere in this world excepts conditions attached or understood previously. One can have FREE tour after it is sponsored by some one else.
Does Bill Kaulitz have his ears pierced?
Yes. He has three earlobe piercings on his left ear and one on his right.
What will happen to a starfish that loses an arm?
A sea star can grow a new one, because it's attached to the center disk!
