Yes, the inheritance of free-hanging earlobes (referred to as the "unattached" phenotype) is often thought to follow a simple recessive pattern, with the unattached earlobes trait being recessive to attached earlobes. This means that to have free-hanging earlobes, an individual would need to inherit two copies of the recessive allele.
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.
Detached earlobes are generally considered to be a dominant trait. This means that if at least one parent has detached earlobes, their child has a high likelihood of also having detached earlobes.
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).
If a boy is born with attached earlobes, it means that he inherited the trait for attached earlobes from at least one of his parents. This trait is determined by genetics and is a dominant trait.
The presence of attached or unattached earlobes is determined by genetics. The trait for unattached earlobes is dominant, meaning that it is more common in the population. This is why more people tend to have attached earlobes.
If both you and your sibling have attached earlobes (aa genotype) and your parents have unattached earlobes, then your parents must both be carriers of the recessive allele for attached earlobes (Aa genotype).
Attached or unattached earlobes.
If they attach directly to the side of the head, they are attached earlobes. If they don't they are unattached.
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.
Attached earlobes is when the ear lobe(the bottom part of your ear that ear-rings are normally fitted) is attached to your face so that it makes a long connection to it. Unattached earlobes are rounded and "hang" from the bottom of your ear.
Yes, the inheritance of free-hanging earlobes (referred to as the "unattached" phenotype) is often thought to follow a simple recessive pattern, with the unattached earlobes trait being recessive to attached earlobes. This means that to have free-hanging earlobes, an individual would need to inherit two copies of the recessive allele.
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.
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.

my dad has attached earlobes, my mum has unattatched earlobes and me and my 2 brothers all have unattatched earlobes. :) hope this helps
Unattached earlobes for sure, attached lobes look silly with earrings. It's a known fact that terrible people have been known to have attached earlobes, like Hitler and Meaghan Burke. They are less wind resistant, people with unattached lobes are faster. Furthermore, its fun to flick unattached lobes, there isn't much you can do with attached lobes. in conclusion, if you have attached lobes i highly recommend making a doctors appointment for plastic surgery to make a slight incision in your lobe.
