The answer is one trait. In Codominant alleles, neither allele is dominant over the other. Both alleles are expressed equally hence no recessive or dominant phenotypes. An example of that of fur color in rabbits where one parent with black fur color and the other with white fur color will produce offspring of black and white fur color. This should not be confused with incomplete dominance whre the two alleles blend in phenotype.Example of incomplete dominance is a parent with straight hair in humans and another with curled hair will produce wavy hair offsprings.
Geologists do not use carbon-based radiometric dating to determine the age of rocks. Carbon dating only works for objects that are younger than about 50,000 years, and most rocks of interest are older than that
Gram positive bacteria stain violet due to the presence of a thick layer of peptidoglycan in their cell walls, which retains the crystal violet these cells are stained with.
