no, because dominant is different from recessive, its impossible to have a dominant-recessive trait because the dominant is when only one copy of the gene is present, while in the recessive a trait that must be contributed by both parents in order to appear in the offspring, in short the dominant is for single parent, while in the recessive is a product of two parents.
A dominate trait
heterozygous?
A mutation can be either recessive or dominant depending on what trait it is.
recessive
It depends on the trait. A dominate trait is not always an advantage, and a recessive trait is not always at a disadvantage.
It depends on the "lenght" of your eyelashes. If you have long eyelashes than it is dominant. If you have short eyelashes than it is recessive.
yes
no not always they can transmit a dominate trait also
the polymorphism is only balanced when the dominate trait is recessive in the cell which came from the daughter cell after division, hence the dominate characteristics.
One dominate, one recessive
if you go back to the beginning of your family tree, maybe a family member had brown eyes brown eyes is a dominate trait and blue eyes is a recessive trait, even tho they may both show the recessive trait they may both poses the brown eyes dominate trait and pass it onto you and you will show it. as the name implies you are more likely to show the dominate trait (75% chance dominate and 255 chance recessive). interestingly enough this means that you do have the recessive blue eye trait but you do not show it.
dominates it (you get the dominant form)
