Genetics of colour blindness. Artwork showing the inheritance of colour-blindness genes. X-chromosomes (yellow) and Y-chromosomes (blue) combine at centre. The normal colour vision allele is a red bar, and the colour-blindness allele is a black bar. The male symbol (arrow) and female symbol (cross) show the male and female parents and the offspring (sons and daughters). The cross-table shows the probability for colour-blindness in the offspring of a normal woman and colour-blind man is half normal sons, and half carrier daughters. This trait is thus classed as X-linked recessive. For an alternative combination, see C009/0295.
