What else can I help you with?
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).
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.
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.
What must be true if a boy is born with detached earlobes?
If a boy is born with detached earlobes, both of his parents must have detached earlobes as well, as this trait is inherited. Detached earlobes are a recessive trait, meaning that both parents must pass on the gene for detached earlobes in order for the child to have them.
In the family tree below people with the recessive trait of attached earlobes are shaded gray.?

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).

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.
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).
Which a students mother Is heterozygous for attached earlobes a recessive trait. The student father Is Also a heterozygous for that trait. What is the percent likelihood that his earlobes are atta?
If both parents are heterozygous for attached earlobes (genotype Ee, where E is the dominant allele for free earlobes and e is the recessive allele for attached earlobes), the possible genotypes for their child can be determined using a Punnett square. The possible combinations are EE, Ee, Ee, and ee. This means there is a 25% chance (1 out of 4) that the student will inherit the genotype ee, resulting in attached earlobes. Thus, there is a 25% likelihood that the student has attached earlobes.
A child is born with attached earlobes but both parents have hanging earlobes. What are the genotypes and phenottypes fot the parents?
The parents would each have the genotype Ee (heterozygous for earlobe attachment) and the phenotype for hanging earlobes. The child inherited the attached earlobe allele from both parents, resulting in the AA genotype and the phenotype for attached earlobes.
What must be true if a boy is born with attached earlobes?
If a boy is born with attached earlobes, it means that he inherited the trait for attached earlobes from at least one of his parents. This trait is determined by genetics and is a dominant trait.
What must a true if a boy is born with attached earlobes?
If a boy is born with attached earlobes, it indicates that he has inherited a specific genetic trait. Attached earlobes are typically considered a recessive trait, meaning that both parents must carry the gene for it to be expressed in their child. Therefore, at least one or both of the boy's parents likely have attached earlobes or carry the allele for the trait.
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.
Can an EE person married to an ee person have children with free earlobes?
Yes, it is possible for two individuals with attached earlobes (ee genotype) to have children with free earlobes. This would depend on the specific genotypes of the parents and the inheritance pattern of the earlobe trait, which is typically considered a simple Mendelian trait. If both parents carry hidden free earlobe genes (Ee), there is a chance that their children may have free earlobes.
If you know that the allele for attached earlobes is recessive and a friend of yours has attached earlobes what do you know about your friends the mothers and the fathers genotype?
If your friend has attached earlobes (recessive trait), then your friend must have two copies of the recessive allele for attached earlobes (aa). This means that both of your friend's parents must be carriers of the recessive allele (Aa) in order to pass it on. Your friend's mother and father would both have one dominant allele (A) for free-hanging earlobes and one recessive allele (a) for attached earlobes.
Is ear shape genetic?
yes, for the most part. The DNA in your genes code for the size, shape and structure of all your physical features- but environmental factors, such as the positioning inside the uterus, can slightly alter the outcome. this is why identical Twins, who have the exact same DNA, end up with different fingerprints
