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.


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


In humans the allele for free hanging earlobes is dominant over the one for attached earlobes What are the possible genotypes of a person with free hanging earlobes?

50%. Heterozygous means that there is two different traits inside of the gene. Therefore you have (aa) for the free earlobes and the other individual with attached (Aa). Drawing a Punnett square you get (aa) in two different spots, creating 50% probability.


Ear lobes 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 if a boy is born with attached your lobes?

He has at least one E allele is correct. I take the quiz

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.

Dominant. he has a homozygous genotype

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.


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.

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.

The genotype of the unaffected children is?

The genotype of the unaffected children can be 1 of 2 different things. The genotype can be either completely dominant or heterogeneous.
