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 carrier woman and normal man is a quarter each normal sons,colour-blind sons,normal daughters,and carrier daughters. This trait is thus classed as X-linked recessive. For an alternative combination,see C009/0293 | |
