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.

The micron or micrometer is a unit of measure for the core in optical fiber, for which the most common diameter is 62.5 micrometers. It is also used to measure the line width on a microchip. Intel's Pentium 4 microprocessors are built using 0.18 or 0.13 micrometer line widths.
