A mutation can be either recessive or dominant depending on what trait it is.
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.
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.
Having six fingers is typically considered a polydactyly trait, which is a rare genetic variation. Whether a trait is dominant or recessive depends on the specific genetic mutation causing it. In polydactyly cases, the inheritance pattern can vary, with some being dominant and others being 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.
Curling ears in cats can be caused by a genetic mutation that is a dominant trait. When a cat inherits the gene for curled ears from one parent, it will display the trait. Curled ears are not a recessive trait because even when present with a normal ear gene, the curled ear gene will dominate and be expressed in the cat's appearance.
Alleles are neither entirely recessive nor entirely dominate. An allele is any one of a number of alternative forms of the same gene on a chromosome.For example: say a flower only blooms either red or white flowers. There is a different allele for each color-- a red allele and a white allele. Now, one color may be dominate over the other recessive gene. For example, if the red color was dominate and the white color was recessive, then those certain alleles would be dominate and recessive, respectively. But alleles in general cannot be either recessive or dominate. It depends on the gene and it depends on the trait.
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.
