heterozygous?
A dominant trait will always hide a recessive trait in an individual's phenotype because the dominant allele is expressed over the recessive allele in the presence of both alleles.
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.
If their genotype contains both a dominant and a recessive allele for a trait.
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.
Dominant traits are expressed over recessive traits because the dominant allele codes for a functional protein that masks the effects of the recessive allele. In a heterozygous individual carrying one dominant and one recessive allele, the dominant allele is expressed, leading to the dominant trait being observed.
A short big toe is typically considered a recessive trait. This means that both parents must contribute a copy of the gene for the short big toe in order for it to be expressed in their offspring.
A dominate trait will most likely take over the recessive.
Both of the alleles must be recessive. The trait expressed is a recessive trait.
recessive trait only appear when an individual is homozygous recessive, both alleles must code for the recessive trait
Dominant trait is a genetics term. A dominant trait is one which will be expressed if one of the parents has the gene for that trait. A recessive trait is one that will be expressed only if both parents carry the trait.
A recessive trait can only be passed along if both parents carry at least one of the recessive genes to the child. If both parents manifest the trait (that is, if both parents have both recessive genes), then the child will manifest (that is, carry both recessive genes and display) the recessive trait. If one parent manifests and the other parent only carries the trait (that is, carries one dominant and one recessive gene) then the child will definitely carry and have a 50% chance of manifesting. If both parents carry the recessive, the child is 25% likely not to carry the trait at all, 50% likely to carry and 25% likely to manifest the trait.
Breed/use only organisms showing the recessive trait for starters. If one of the parents or progenitor lines show the dominant trait then don't use their offspring. If the offspring of one of the oranisims show the dominant trait then remove both the parent of this offspring and this offspring showing the dominant trait from your program.
