its neither. its a learned skill. i can do it, and i learned to by holding one eyebrow up, with my finger, and learning to adapt from that. you use muscle in your face when you do it. if you want to learn, wrinkle your forehead that will help you.
It cannot be a dominant trait. You probably know of people who had unibrows while their parents didn't. If you have a heterozygous set of genes, meaning one of a kind, and unibrows are dominant, then it would mean you had one. But since the trait must have come from one of your parents, everyone with a unibrow would have a parent with one.
I believe having a unibrow is recessive but I have found other sources that say that it is dominant so I am very confused as well.

Recessive
If you have 2 dominant alleles, the gene will be dominant, if you have 2 recessive alleles, the gene will be recessive. But if you have 1 recessive and 1 dominant, the Dominant allele will mask the recessive one.
heterozygous recessive
The different forms of a gene are called alleles. In Mendelian genetics, a gene has a dominant allele and a recessive allele. The dominant allele masks the recessive allele if present. So there are two possible dominant genotypes: homozygous dominant, in which both dominant alleles are present; and heterozygous, in which one allele is dominant and the other allele is recessive. The only way to express a recessive trait is to have the homozygous recessive genotype.
explain how dominant genes work
dominant allele will overthrow a recessive one
Alleles can be dominant or recessive
There is dominant and there is recessive. There is no dominant recessive. A dominant gene will always be expressed when present, such as in the homozygous dominant genotype (RR), or heterozygous genotype (Rr). A recessive allele is only expressed when the genotype is homozygous recessive (rr).
is malignant melanoma dominant or recessive
Dominant traits are the traits that mask the recessive traits. The dominant traits are stronger than recessive!
Dominant definitely not dominant. It is recessive objectively and subjectively and unequivocally.
If you have 2 dominant alleles, the gene will be dominant, if you have 2 recessive alleles, the gene will be recessive. But if you have 1 recessive and 1 dominant, the Dominant allele will mask the recessive one.
