Whether or not an ear lobe is attached at its base or not depends on whether or not that person's parents had attached earlobes or not. If both parents have attached earlobes, then their children will also have attached earlobes. If both parents have detached earlobes, then their children will also have detached earlobes. But if one parent has detached earlobes, while the other has attached earlobes, their child's earlobes may be detached, attached, or only slightly attached.
This is because each parent provides part of the DNA (deoxyribonucleic acid) molecules that exist at the center of almost every human cell. Since the cells of the body don't "know" anything, they just follow the "instructions" that DNA provides them by building themselves according to how the DNA molecule says they should be built.
How this actually works is a complicated chemical process that would be better answered in a separate question, but you don't need to know how it works, only that the result is this - children get some instructions for how to build their body from their mother, and some from their father. If the instructions agree, then the cells that make up the ear will grow a definitely attached or detached earlobe. If the instructions in the child's DNA disagree, then you might get a mix, or the cells might end up paying attention only to one set of instructions or another.
What else can I help you with?
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.
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.
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 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.
Some people have attached ear lobes and some people have free ear lobes. The differences in these traits are caused by?
diffrent genes you idiot
Can you tell if your parents are your parents by their ear lobes?
....
Do ear lobes have nerves?
certainly, you can try it.
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
