I would also like to know what does this mean? I have one attached and one detached ear lobe aswell..
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.
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.
No.
There is no scientific evidence to support the idea that long earlobes are connected to longevity or a longer life span. Earlobe length is primarily determined by genetics and does not have any direct correlation with life expectancy.
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.
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.
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
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
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.
its earlobes earlobes are always the answer
He has a homozygous genotype
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).
