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.

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.


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.


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 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 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


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.


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).


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.


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
