A trait is dominant if it continues to be expressed in the heterozygous as well as the homozygous state. Recessivetraits are only expressed in the homozygous state.

A dominant trait is expressed when an individual has one or two copies of the dominant allele, while a recessive trait is only expressed when an individual has two copies of the recessive allele. Dominant traits mask the expression of recessive traits in heterozygous individuals.

What will always hide a recessive trait?
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.
How do you get brown eyes from blue eyed parents?
Brown eye color is a dominant trait, meaning it only requires one brown-eyed parent to pass on the gene for brown eyes. If both parents carry a recessive brown eye gene (not necessarily expressing the trait), there is a possibility of them passing this gene on to their child, resulting in brown eyes.
How do dominate traits over power the recessive?
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.
Are tight eyelids a dominate or recessive trait?
Trait inheritance is more complex than a simple dominance or recessive model. The expression of eyelid tightness can be influenced by multiple genes and environmental factors, making it difficult to categorize as solely dominant or recessive.
If the sickle cell trait were a dominant trait rather than a recessive one could it still be balanced polymorphism?
Yes, if the sickle cell trait were a dominant trait, it could still be a form of balanced polymorphism. In a dominant scenario, individuals with one copy of the allele would express the trait. In this case, heterozygous individuals would have the sickle cell trait, potentially providing a selective advantage against malaria, similar to how carriers of the recessive trait do in the current situation.
What contains both a dominate trait and a recessive trait?
heterozygous?
Would a mutation be a dominate or a recessive trait?
A mutation can be either recessive or dominant depending on what trait it is.
What will always hide a recessive trait?
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.
A male will always transmit a recessive trait to his son?
no not always they can transmit a dominate trait also
How can the alleles that control that trait be described?
One dominate, one recessive
An individual heterozygous for a trait and an individual homozygous recessive for the trait are crossed and produce many offspring?
The offspring has a 50% chance of the dominate trait (while being heteroygous) and a 50% chance of having the recessive trait ( homozygous recessive).
What gene won't display its trait in the prescience of a dominate trait?
A recessive gene will not display its trait in the presence of a dominant trait. A recessive gene only expresses its trait when paired with another copy of the same recessive gene.
What is the difference between a dominant trait and a recessive trait?
A dominate trait will most likely take over the recessive.
What does recessive mean in genetic term?
Recessive is the opposite of dominate, not as powerful of an influence on whether or not it will become the chosen trait on a punnett square.
Recessive allele different from dominate allele?
You need two recessive alleles to get their trait, but only one dominant allele to get that trait. A dominant allele basically overrides a recessive one if they are together, but the recessive gene can show up in offspring.
What is the difference between the dominant and recessive allele for a trait?
An individual must have 2 recessive alleles in order for a trait to show up. One must only have 1 dominant allele in order for a trait to occur.
What do you call a organism that possesses one dominate and one recessive genes for a single trait?
heterozygous
