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.
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.
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.
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.
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.
heterozygous?
A mutation can be either recessive or dominant depending on what trait it is.
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.
no not always they can transmit a dominate trait also
One dominate, one recessive
The offspring has a 50% chance of the dominate trait (while being heteroygous) and a 50% chance of having the recessive trait ( homozygous recessive).
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.
A dominate trait will most likely take over the recessive.
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.
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.
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.
