A sex linked dominant trait could be on the X chromosome of either parent and the phenotype of any individual carrier would be that of the dominant trait. A
father with the dominant characteristic on his single X chromosome would produce daughters that are 100% carriers and would not pass the characteristic on to his sons.
A mother who is a dominant X linked carrier would pass the dominant characteristic on to half hersons and half her daughters all of which would
show the trait phenotypically.
A sex linked recessive father would produce 100% carrier daughters. His sons
would not get the recessive allele from him.
A sex linked recessive carrier (heterozygous) mother would pass the trait on
to 50% of her children and 50% of her sons would show the recessive trait
genetics.
The answer is that The difference is that dominant dominates, and recessive is dominated.
They are the same
dominant-appears in first generation recessive-seems to dissapear
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.
Dominant alleles override recessive alleles. For instance, if there is both a dominant allele and a recessive allele present the dominant allele will be the trait that you end up with. If you have two recessive alleles, then you will have the recessive trait. :::::::::::::::brown eyes overrided blue eyes, because they are darker:::::::::::::::::: usually a darker color overpowered/override the lighter ones....i dont really know why but my science teacher said so......

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.
the dominant trait is the stronger one and the recessive trait is the weaker one
Dominant is stronger than recessive. So you can only have the phenotype ( visual characteristic ) of a recessive allele if you have 2 recessive alleles in your DNA , and other combination the dominant allele would be predominant

There are no such things as dominant and recessive genes. There are only dominant and recessive alleles. Dominant alleles are parts of a gene that present its features over the recessive allele, which is the one that is always masked by the dominant allele. The recessive allele's trait only shows if both of the alleles in a trait are recessive.
The genotypes TT and Tt represent different combinations of alleles for a particular gene. TT is homozygous dominant, meaning it has two identical dominant alleles, while Tt is heterozygous, containing one dominant allele (T) and one recessive allele (t). This difference can affect the expression of traits, with TT typically exhibiting the dominant phenotype and Tt also showing the dominant phenotype, but potentially carrying the recessive trait.
