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.

Is free ear lobe trait autosomal or sex linked?
Yes, attached ear lobes are autosomal recessive.
Free earlobes in humans is a dominant trait if two parents with free earlobes have children with attached earlobes the genotype of the parents must be?
the genotype would be for the mom Ee and for the dad it would be Ee.
What ratio of genotypes and phenotypes are found after two heterozygous indivividual are crossed for a trait of earlobes?
Genotypes (phenotype) 25% homozygous dominant (free earlobes) 25% homozygous recessive (attached earlobes) 50% heterozygous (free earlobes) 75% phenotypically dominant (free earlobes) 25% phenotyically recessive (attached earlobes) Ratios Genotype 1:1:2 Phenotype 3:1
What is two dominant alleles called?
In eyes, it would be brown is dominant, and blue is recessive. Free earlobe allele is said to be dominant over the attached earlobe allele. When an organism has two dominant alleles for a trait, it is called homozygous dominant. Two recessive alleles for a trait is homozygous recessive.
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.
Have both parents got to have ear lobes to have a child with lobes?
No, (free) earlobes follow a simple genetic dominance relationship, where free earlobes are dominant over attached earlobes. Meaning that having one parent with free earlobes suffices for the child to also share that trait.
Is free ear lobe trait autosomal or sex linked?
Yes, attached ear lobes are autosomal recessive.
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
What is an example of a dominant human trait?
Dominant traits are more common. For example, brown hair and eyes are good examples of dominant traits. Another example of a dominant trait are your earlobes! Free earlobes are more common than attached earlobes.
You have one free earlobe and one attached how does that happen?
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.
Free earlobes in humans is a dominant trait if two parents with free earlobes have children with attached earlobes the genotype of the parents must be?
the genotype would be for the mom Ee and for the dad it would be Ee.
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

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 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.
In your own words what does the term recessive trait mean?
A recessive trait is the opposite of a dominant trait. A dominant trait is the trait that overpowers another trait- represented by a capital letter. The recessive trait is the trait that is weaker, and being overpowered- represented by a lowercase letter. For example, if one person had a recessive trait for detached earlobes, it would be represented as " aa ",. If someone had a dominant trait for attached earlobes (meaning they had free earlobes), it would be represented as "AA"or " Aa "
