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?

Are ear lobs that are attached dominant or recessive?
It was said earlier that, "Unattached earlobes are the dominant trait, twice as many people have unattached earlobes compared to attached." There is not actually any real proof that unattached earlobes are dominant. While more people may have unattached earlobes, attached earlobes are dominant. This was proved in a pedigree which covered three generations of extended families.
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.
Why do more people have attached rather than unattached earlobes?
Cause attached earlobes are the dominant trait. Unattached earlobes are reccessive.
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
Is detached earlobes recessive or dominant?
Dominant. he has a homozygous genotype

How can you tell if you have attached or detached earlobes?
If they attach directly to the side of the head, they are attached earlobes. If they don't they are unattached.
You have one free earlobe and one attached how does that happen?
This is called co-dominance. It is when neither alleles are dominant or recessive. Therefore, both traits are expressed. Ex. Some horses have two hair colors. For example, if two hairs are next to each other, one hair would be red, and the other would be brown. I am taking a class on this and free/attached earlobes are not co-dominant, its a recessive/dominant trait. I also have one free and one attached earlobe and am not sure how it happens, all i know is that free earlobes are dominant and attached are recessive.
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 is the probability that a father produces a gamete with the allele for attached earlobes if he has one allele for detached earlobes and one allele for attached earlobes?
50%
Why do more people have attached rather than unattached earlobes?
Cause attached earlobes are the dominant trait. Unattached earlobes are reccessive.
What percentage of people in United States have detached earlobes?
Studies show that roughly seventy percent of people in the world have detached earlobes, leaving thirty percent with attached earlobes. However, this is only a rough estimate based on data collected.
What percentage of people have detached earlobes?
it is a dominant trait so about 75% i would say
