Could a couple who both have attached earlobes have a child with free earlobes Why or why not?

Could a couple who both have attached earlobes have a child with free earlobes Why or why not?

If the myth were true, two parents with attached earlobes could not have a child with a free earlobe. There are slightly more A offspring from A x A matings, but the large numbers of F offspring from A x A matings and A offspring from F x F matings indicate that this is not a one-locus, two-allele trait.

What is the chance that their child would have unattached earlobes?

That child will have free earlobes. There are two boxes with “Ee” which means that there is a 50% chance (two 25%s combined) that the child will get “Ee”, one dominant gene and one recessive gene. That child will have free earlobes, but will carry the gene for attached earlobes, just like her parents.

Are detached earlobes inherited or acquired?

If earlobes hang free, they are detached. Some scientists have reported that this trait is due to a single gene for which unattached earlobes is dominant and attached earlobes is recessive. Other scientists have reported that this trait is probably due to several genes.

Are attached earlobes rare?

Attached earlobes are not rare but are also not commonly found. Earlobes of such type are small in size and are attached directly to the side of the head. The recessive allele is expressed to form an attached earlobe.

Are unattached earlobes rare?

Free earlobes are the most common form of ear lobes in humans. If the parents’ genes express the dominant allele, the child will be born with free earlobes. In most cases, the allele is regnant to the free lobes compared to attached lobes.

Can you have both attached and unattached earlobes?

No, they won’t have one attached and one unattached. In the case of the earlobe genes, one is dominant over the other. This means that when they are both together, one gene will be expressed and the other will not be expressed.

Are attached or detached earlobes more common?

In one of the first earlobe studies, scientists concluded that unattached earlobes were dominant over attached ones. They based this on two families. Everyone in the first family had attached earlobes and everyone in the second had unattached ones.

What are attached and detached earlobes?

Earlobes can be described as “free” or “attached.” Attached earlobes are connected directly to the head, while free earlobes hang down below that point of connection.

What do unattached earlobes mean?

If your earlobes form a smooth line where they connect to your head, they are considered attached. If your earlobes form a noticeable notch or angle where they join the head, they are referred to as unattached or free earlobes by some scientists.

Can you have an attached and detached earlobe?

Generally, earlobes are either attached to the side of the head, or detached and only connected to the ear itself. You might be surprised to learn that earlobe shape is influenced by dozens of genetic factors.

Is it common for parents to have an unattached earlobe?

Even though ear lobe genetics hasn’t been studied a whole lot, the little bit that has been done shows it is pretty complicated. This means that it isn’t uncommon for parents with attached earlobes to have kids with unattached lobes. Or even for parents to have kids with one attached and one unattached earlobe! So what’s going on here?

Can you have a child with a dominant earlobe?

Of course, given all of this, two parents with a recessive trait can’t have a child with a dominant one. So two parents with attached earlobes should not be able to have a child with unattached ones. Except that sometimes they do. Which means that earlobes are more complicated than is usually advertised.

What does it mean if your earlobes are attached, or?

If earlobes hang free, they are detached. If they connect directly to the sides of the head, they are attached. Earlobe attachment is a continuous trait: while most earlobes can be neatly categorized as attached or unattached, some are in-between. Although some sources say…

Is it true that earlobes are recessive in humans?

However, all of the offspring of A x A matings had attached earlobes, and there were no F x F matings, so his data are consistent with either free or attached being dominant. Powell and Whitney (1937) looked at one family and concluded that attached earlobes were recessive.
