sauerkraut was renamed liberty cabbage to remove the german connotation much like what george w bush and the republicans did to french fries by renaming them freedom fries # french fries # freedom fries # sauerkraut # germany # france # george w bush # patriotism
The most common type of red-green color perception defect is due to a mutation on the X-chromosome (i.e. a red-green color blind allele). X-linked red-color blindness is a recessive trait. Females heterozygous for this trait have normal vision.The color perception defect manifests itself in females only when it is inherited from both parents.oth X-chromosomes must carry the mutant allele for the females to be color blind. Red-green color blind females are homozygous for the recessive allele. Females with one mutant allele and one normal allele are heterozygous carriers.
The gene affects color blindness, not the other way around. It is sex linked and recessive, males that are color blind have only one gene on the X chromosome, the Y chromosome is missing the like gene.A recessive gene on the X chromosome causes men to be color blind, a recessive gene on both the X and Y chromosomes causes females to be colorblind.This makes more men colorblind than women. And it is sex linked in that the woman contributes the X chromosome to the offspring. At least that is the way I remember it.olorblindness is a defective gene on the X chromosome. Females have 2 x chromosomes, thus one can serve as a backup for a defective gene. However, the Y chromosome in males is almost totally defective, thus does not have a backup.
