The brown allele is always dominant over the green and blue alleles, the green allele is always dominant over the blue allele, and the blue allele is always recessive. Because of this, it is possible for two brown-eyed parents to have a child with a different eye color than theirs.For two brown-eyed parents to have a blue-eyed child, for example, the mother and father would need to pass on a pair of blue alleles each to their offspring.he brown allele is always dominant over the green and blue alleles, the green allele is always dominant over the blue allele, and the blue allele is always recessive. Because of this, it is possible for two brown-eyed parents to have a child with a different eye color than theirs.
By Anne Marie Helmenstine, Ph.D. Micron Definition: A micron is a unit of length equivalent to a millionth of a meter. 1 micron = 1 Î¼m = 10 -6 m. Also Known As: micrometer, micrometre, Î¼m. Examples: Red blood cells are approximately 10 microns in diameter. Human hair is between 10 and 100 microns in diameter.
In chemistry, a hydron is the general name for a cationic form of atomic hydrogen, represented with the symbol H+ . The term proton refers to the cation of protium, the most common isotope of hydrogen.nlike other ions, the hydron consists only of a bare atomic nucleus. The hydron (a completely free or naked hydrogen atomic nucleus) is too reactive to occur in many liquids, even though it is sometimes visualized to do so by students of chemistry.
