No, I think you have your terms confused. The terms "dominant" and "recessive" are applied to alleles of a genotype. A genotype is an expression (using upper- and lower-case letters) that shows what...
dominant traits show up in the first generation so any disorders have a 50% percent chance of showing up in offspring. recessive traits skip a generation therefore any diseases would have on a 25%...
They're not necessarily, but they can be. When a recessive trait is more common, it likely because it was advantageous to have that trait so the species evolved to have more of it in the gene pool....
It depends on the trait. If the dominant genotype is selected for more often than the recessive genotype, then the dominant allele will become more common in the gene pool. If the recessive genotype...
