Is it possible to have two different earlobes?
Yes, variations in earlobe shape and size are common due to genetics. It is possible to have two different earlobes on each side of the body.
What part of your body is always the same length as your thumb?
Your earlobes are always the same length as your thumb.
Are earlobes a recessive gene?
Yes, the inheritance of free-hanging earlobes (referred to as the "unattached" phenotype) is often thought to follow a simple recessive pattern, with the unattached earlobes trait being recessive to attached earlobes. This means that to have free-hanging earlobes, an individual would need to inherit two copies of the recessive allele.
Is detached earlobes recessive or dominant?
Dominant. he has a homozygous genotype
What is the phenotype of a man who has 2 parents with free hanging earlobes if one parent is homozygous and the other parent is heteroygous... what are his possible genotypes?
The man could have either free hanging or attached earlobes. His possible genotypes could be either homozygous for free hanging earlobes (LL) or heterozygous for free hanging and attached earlobes (Ll).
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?
If two parents with free earlobes have a child with attached earlobes, both parents must have the genotype of heterozygous (Ee) for earlobe shape. Free earlobes (E) is dominant over attached earlobes (e), so the presence of attached earlobes in their child indicates that both parents are carriers of the recessive allele for attached earlobes.
Why do humans have earlobes?
Human earlobes really have no practical function they are a "leftover" of human evolution, but earlobes have procreational usage if you like earings and gauging...
Is it possible to have two different earlobes?
Yes, variations in earlobe shape and size are common due to genetics. It is possible to have two different earlobes on each side of the body.
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 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.
What part of your body is always the same length as your thumb?
Your earlobes are always the same length as your thumb.
What are some questions about condensation?
its earlobes earlobes are always the answer
Earlobes can be either attached or detached. The allele for attached earlobes is recessive and the allele for detached earlobes is dominant. What must be true is a boy is born with attached earlobes?
He has a homozygous genotype
Both you and your sister or bother have attached earlobes yet your parents have unattached earlobes unattached earlobes are dominant over attached earlobes what are the genotypes of your parents?
If both you and your sibling have attached earlobes (aa genotype) and your parents have unattached earlobes, then your parents must both be carriers of the recessive allele for attached earlobes (Aa genotype).
Why do more people have attached rather than unattached earlobes?
The presence of attached or unattached earlobes is determined by genetics. The trait for unattached earlobes is dominant, meaning that it is more common in the population. This is why more people tend to have attached earlobes.
What is the ratio of free earlobes to attached earlobes?
The ratio is approximately 4:1, with free earlobes being more common than attached earlobes in the general population.
What is the link between a chickens eggs and its earlobes?
The color of the chickens earlobes is usually an indicator of what color egg they will lay. Red earlobes - Brown, Blue, or Green eggs Blue earlobes - Blue or Green eggs White Earlobes - White eggs
