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 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.
What happens when a person receives on alle for attached earlobes and one for unattached earlobes?
there one alle for free ear-lobes and another allele for attached if your gene for ear-lobes is made up of two alleles for free ear-lobes your ear-lobes are NOT attached and if you have two attache-ear-lobes alleles your ear-lobes are attached
Can ear lobes shrink?
Yes, ear lobes can shrink over time due to factors such as weight loss or aging. Piercings in the ear lobes can also contribute to stretching and potentially reducing the size of the lobes. If you notice significant changes in your ear lobes, it's recommended to consult a healthcare professional for advice.
What are the chances of a heterozygous recessive male producing offspring with curled ears?
A heterozygous recessive male has one dominant allele and one recessive allele for a trait, like curled ears. If the curled ear trait is recessive, it will only be expressed in offspring if they inherit two recessive alleles (one from each parent). Therefore, if the mother is also heterozygous or homozygous recessive, there is a chance for curled-eared offspring, but if she is homozygous dominant, the male cannot produce curled-eared offspring. The specific chances depend on the genotype of the female parent.
Are ear points dominant or recessive?
Ear points, or the presence of colored markings on the ears of certain animals (like some dog breeds), are typically considered a dominant trait. This means that only one copy of the allele is needed for the trait to be expressed. However, the expression of traits can vary among species and specific breeds, so it's essential to consult breed-specific genetics for definitive information.
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.
Is the lop ear in rabbits recessive or dominant?
Yes, the lop ear gene is recessive since it is a mutation.
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.
What happens when a person receives on alle for attached earlobes and one for unattached earlobes?
there one alle for free ear-lobes and another allele for attached if your gene for ear-lobes is made up of two alleles for free ear-lobes your ear-lobes are NOT attached and if you have two attache-ear-lobes alleles your ear-lobes are attached
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.
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.
Can ear lobes shrink?
Yes, ear lobes can shrink over time due to factors such as weight loss or aging. Piercings in the ear lobes can also contribute to stretching and potentially reducing the size of the lobes. If you notice significant changes in your ear lobes, it's recommended to consult a healthcare professional for advice.
If both parents have detached ear lobes can they have a child with attached ear lobes?
Yes they can, because they could get the genes from a grandparent, or even farther back if they didn't have detached ear lobes.
Are ear lobs that are attached dominant or recessive?
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.
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 it normal for chickens to have green ear lobes?
Yes, it is normal for some chicken breeds to have green or bluish ear lobes. The color of the ear lobes can vary depending on the breed. It does not indicate any health issues.
Do ear lobes contain fat?
Yes, ear lobes do contain fat, along with connective tissue and skin. The fatty tissue contributes to the overall structure and flexibility of the ear lobe. This composition can vary from person to person, affecting the size and shape of their ear lobes.
