I would like to know what people think it means when someones earlobe is attached to their face versus not attached

Loading...

attached earlobes and free earlobes are a dominant-recessive gene
attached being the recessive, meaning fewer people have it

it is nonfatal and there is nothing wrong with having attached earlobes..i have them 8)

Recessive does NOT necessarily mean fewer people have it.

Looks like someone uses recessive math.

It's true, recessive does NOT necessarily mean fewer people have the trait. The creation of new combinations of genetics is subject to a whole slew of things, including: chance, mating preferences, natural selection,... which in the end means that whether or not a trait is recessive or dominant does not mean fewer or more people will carry it.

Dominant alleles are called dominant for a reason. More people will display the dominant allele of the gene worldwide in their phenotype BECAUSE of the way genetics and inheritance works. True it does not necessarily mean that fewer people have the trait in a small sample size or in places where people are secluded from other populations (think Amazon tribe), but worldwide it does. Maths would actually predict that in the future recessive traits such as attached earlobes would cease to exist altogether. If two people mate who are heterozygous for the earlobe trait (Rr) then there is a 25% chance of their offspring displaying the recessive trait in their phenotype, to give one example.

I'm reading for a biology degree so I should know.

Hello
I have a query pertaining to the genetic variation of attach and free lobes...
How does Dominant and Recessive traits (genotype) influences these lobes phenotype?
