Earlobes that are attached to the face rather than ones that hang freely (de-attached)
yes!
Idk:/.. i Need hlep with this too..!! Please Help Meh..!!:)
lets use "A" Aa and Aa aa
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
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.
He has a homozygous genotype
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.

Cause attached earlobes are the dominant trait. Unattached earlobes are reccessive.
88:69
the gene is not shown in their chara ter
If they attach directly to the side of the head, they are attached earlobes. If they don't they are unattached.
50%
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.
Earlobes that are attached to the face rather than ones that hang freely (de-attached)
Whether or not the earlobe is attached is a genetically inherited trait and so you would need to look at earlobes in your, and your partner's, families.
