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 possible genotypes HH and Hh. 50% homozygous for hanging earlobes (HH), and 50% heterozygous for hanging earlobes (Hh).

A child is born with attached earlobes but both parents have hanging earlobes. What are the genotypes and phenottypes fot the parents?
lets use "A" Aa and Aa aa
What are the phenotype attach earlobes?
Earlobes that are attached to the face rather than ones that hang freely (de-attached)
Is detached earlobes recessive or dominant?
Dominant. he has a homozygous genotype
What are the Genotypes for free and fixed ear lobes in human beings?
There are none. Earlobes fuse to the head during the development stages of a baby
Predict what genotype the children will have if one parent is homozygous recessive for earlobes and homozygous dominant for hairline (eeWW) and the other parent is homozygous dominant for unattached earlobes and homozygous recessive for hairline (EEww )?
The only possible outcome is EeWw, which will express the dominant genes but carry the recessive ones. They get one chromosome from each parent, but since the parents all have matching chromsomes in this case then it doesn't matter which one they get. Since one parent has EE, E is the only one that can be passed on. Since the other has ee, they can only pass on e. Therefore, the child can only possible have Ee, as they get one from each parent.
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
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.
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?
the gene is not shown in their chara ter
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

Whats the phenotype of a stronger allele?
The allele which have dominant genes or whose genes can express themselves in presence or its corresponding gene in F1 expressions is the strongest of two, allthough no whole allele is strongest but its part of gene which carry that ability

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 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.
