Is earlobe types discrete or continuous?

Here, when you organize your ear cards into a continuous spectrum, you're describing earlobe shape as a continuous trait, ranging from free to attached. Scientists usually consider continuous traits to be complex traits.

What is an earlobe?

The earlobe (lobulus auriculae) is the soft, fleshy part of the outer ear. Without cartilage, the earlobe contains a large blood supply with many nerve endings. For some, the earlobes are an erogenous zone.

What are the different types of ear lobes?

There are two primary types of earlobes found in humans, which include free earlobes and attached earlobes.

What is the genotype for attached earlobes?

Could be EE; free earlobes. Could be Ee; also free earlobes. Could be ee; attached earlobes. The expression of one's genotype, such as EE, Ee or ee, is called one's phenotype.

Are earlobes dominant or recessive?

If they attach directly to the side of the head, they are attached earlobes. Some scientists have reported that this trait is due to a single gene for which unattached earlobes is dominant and attached earlobes is recessive.

Continuous vs Discrete Data

Which earlobe is dominant?

Two parents, both with unattached earlobes, had a child with attached earlobes. What are the chances that their next child will have attached earlobes?

Is attached earlobes autosomal?

Autosomal Traits

Consider earlobe attachment. A single autosomal gene with two alleles determines whether you have attached earlobes or free-hanging earlobes. The allele for free-hanging earlobes (F) is dominant to the allele for attached earlobes (f).

Is a earlobe a phenotype?

The phenotype of an organism is the way that organism looks or the trait that it has. If a person's genotype was Ee, then their phenotype would be unattached earlobes.

How many types of ears are there?

The ear has three main parts: external ear, middle ear and inner ear. They all have different, but important, features that facilitate hearing and balance.

What does no earlobes mean?

Why are my ears different shapes?

Acquired ear differences usually result from traumas that lead to either a missing piece of the ear or a misshapen ear that is the result of significant scarring. Contour differences of the ear come in as many different forms as there are ears.

Are all ears different?

Ears are actually unique to each and every person, so much so that they are comparable in uniqueness to the fingerprint. Research has even suggested that ears may be a more effective identification tool than a fingerprint through the use of a new “image ray transform” technology.

What is structure of ear?

The ear is divided into three parts: the external, middle and inner ears. The transmission of sound takes place in the external and middle ears. The inner ear houses the cochlea (organ of hearing) and the peripheral vestibular system (organ of balance)

Which of the following would be the genotype of an individual who has attached earlobes if having detached earlobes is a dominant trait?

If both parents have detached earlobes, and both are heterozygous, then the possible offspring outcomes will be: Remember: e = recessive, attached earlobes; E = dominant = detached earlobes.

What is the difference between attached earlobes and unattached?

Attached Earlobes and Free Earlobes

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.
