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.

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.
Micro (symbol Âµ) is a unit prefix in the metric system denoting a factor of 10 â6 (one millionth). Confirmed in 1960, the prefix comes from the Greek Î¼Î¹ÎºÏÏÏ (mikros), mikrÃ³s meaning. Small the symbol for the prefix comes from The greek letter (Î¼). mu
