Where do attached earlobes come from?

Attached earlobes Earlobes of such type are small in size and are attached directly to the side of the head. This kind of lobe's structural formation is due to the absence of the dominant allele in the chromosomes. The recessive allele is expressed to form an attached earlobe.

Do Europeans have attached earlobes?

Are attached earlobes recessive?

You have free earlobes, which means you have at least one copy of the dominant allele. You could be either FF or Ff. And your parents both have attached earlobes, which is the recessive trait.

What are inherited traits?

Inherited, as related to genetics, refers to a trait or variants encoded in DNA and passed from parent to offspring during reproduction. Inheritance is determined by the rules of Mendelian genetics.

What percent of the population has attached earlobes?

Girls receive an X-chromosome from each parent, therefore their X-linked traits will be partially inherited from dad, too. Boys, on the other hand, only receive a Y chromosome from their father and an X chromosome from their mother. That means all of your son's X-linked genes and traits will come straight from mom.
