In most cases colour blindness is usually passed down from your parents, therefore making it a hereditary condition but no tin all cases. Red/green partial blindness is gone from mother to child on the 23rd chromosome, which is known as the sex chromosome in light of the fact that it likewise decides sex. Chromosomes are structures, which contain qualities – these contain the guidelines for the advancement of cells, tissues and organs. On the chance that you are partially colour blind it implies means that your cone cells are broken and the cone cells may be missing, or less delicate to light or it might be that the pathway from your cone cells to your cerebrum has not grown accurately. As the faulty gene can only be found on the X chromosome it means for a male to be colour blind it only has to be found on his single X chromosome where as for a female it has to be found on both her X chromosomes. If the faulty gene is on only one of the females X chromosomes she will not be colour blind but she is known as a carrier.
“A colour blind boy can’t receive a colour blind ‘gene’ from his father, even if his father is colour blind, because his father can only pass an X chromosome to his daughters.
A colour blind daughter therefore must have a father who is colour blind and a mother who is a carrier (who has also passed the faulty ‘gene’ to her daughter). If her father is not colour blind, a ‘carrier’ daughter won’t be colour blind. A daughter can become a carrier in one of two ways – she can acquire the ‘gene’ from a carrier mother or from a colour blind father” (Colour Blind Awareness, 2015).
