This is called co-dominance. It is when neither alleles are dominant or recessive. Therefore, both traits are expressed.
Ex. Some horses have two hair colors. For example, if two hairs are next to each other, one hair would be red, and the other would be brown.
I am taking a class on this and free/attached earlobes are not co-dominant, its a recessive/dominant trait. I also have one free and one attached earlobe and am not sure how it happens, all i know is that free earlobes are dominant and attached are recessive.
What else can I help you with?
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
Which alleles would a child have to inherit to have attached earlobes?
To have attached earlobes, a child must inherit two recessive alleles for the earlobe trait, typically represented as "ee." If the child inherits one dominant allele (E) for free-hanging earlobes and one recessive allele (e), they will display the free-hanging trait instead. Therefore, both parents must either be homozygous recessive (ee) or carry at least one recessive allele (Ee) for the child to have attached earlobes.
Arlobes can be either attached or detached. The allele for attached earlobes is recessive (e) and the allele for detached earlobes is dominant (E). What must be true if a boy is born with attached ear?
If a boy is born with attached earlobes, he must have inherited two recessive alleles (ee), one from each parent. This means that both parents must either be carriers of the recessive allele (Ee) or express the attached earlobe phenotype themselves (ee). Therefore, at least one of the parents must have the recessive allele for attached earlobes.
What is the meaning of detached earlobes?
Detached earlobes refer to earlobes that hang freely and are not connected to the side of the head. This trait is a genetic variation, with earlobe shape being influenced by heredity. Detached earlobes are often considered a dominant trait, meaning they can be passed down from one generation to the next. In contrast, attached earlobes are connected directly to the head without a free-hanging section.
In the family tree below people with the recessive trait of attached earlobes are shaded gray. What must be true about the person labeled A?
Person A must carry at least one dominant allele for unattached earlobes, as they are not shaded gray and therefore do not express the recessive trait of attached earlobes. If A had two recessive alleles, they would exhibit the attached earlobe trait. Additionally, A could be homozygous dominant or heterozygous for the trait, meaning they might have a parent or sibling with attached earlobes as a result of inheriting the recessive allele.
What is a free earlobe?
A free earlobe is an earlobe that is not entirely attached to the head. The gene for free earlobes is dominant in most cases.
What percent of people have one attached and one detached earlobe?
Well, isn't that just a happy little coincidence! It's estimated that around 10-12% of people have one attached and one detached earlobe. Just like how every tree in our painting is unique, each person's features are special and beautiful in their own way.
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 the smallest bone located in your earlobe?
No, the earlobe is just a fleshy skin tag. For some people it is attached and small. The smallest bone is the stapes or stirrup. It is one of the three auditory ossicles of the middle ear and it enters the cochlea of the inner ear.
If both of the parents have attached earlobes what is their genotype?
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.
Arlobes can be either attached or detached. The allele for attached earlobes is recessive (e) and the allele for detached earlobes is dominant (E). What must be true if a boy is born with attached ear?
If a boy is born with attached earlobes, he must have inherited two recessive alleles (ee), one from each parent. This means that both parents must either be carriers of the recessive allele (Ee) or express the attached earlobe phenotype themselves (ee). Therefore, at least one of the parents must have the recessive allele for attached earlobes.
When cutting hair should you use your temples as a guide to cut the top?
That's one way of doing it. Another is to image a line going from earlobe to earlobe
What is the probability of having a child with attached earlobes when an individual with attached earlobes mates with an individual heterozygous for free earlobes?
Attached earlobes are a recessive trait. When one parent has attached earlobes and the other is heterozygous for free earlobes, the chances of any particular offspring having attached earlobes is fifty percent.
Where do you get a free Justin Bieber shirt?
That is highly not going to happen. You have to buy one, they are not free.
Can an allergic reaction cause one earlobe redness?
Yes. They don't have to be on both sides of the head.
If you go to Bulgaria would you get a tour?
No FREE meal anywhere in this world excepts conditions attached or understood previously. One can have FREE tour after it is sponsored by some one else.
In the family tree below people with the recessive trait of attached earlobes are shaded gray. What must be true about the person labeled A?
Person A must carry at least one dominant allele for unattached earlobes, as they are not shaded gray and therefore do not express the recessive trait of attached earlobes. If A had two recessive alleles, they would exhibit the attached earlobe trait. Additionally, A could be homozygous dominant or heterozygous for the trait, meaning they might have a parent or sibling with attached earlobes as a result of inheriting the recessive allele.
