Question

a person suffering from colour blindness cannot recognise

Answer 1

Answer:

Color blindness is not a form of blindness at all, but a deficiency in the way you see color.If you are colorblind, you have difficulty distinguishing certain colors, such as blue and yellow or red and green.

Explanation:

Colour blindness is a sex linked recessive disorder due to defect in either red or green cone of eye resulting in failure to discriminate between red and green colour . This defect is due to the mutation in certain genes present in X chromosome. it occur in about 8% of males and only about 0.4% of females. this is because the genes that lead to red green colour blindness are on the X chromosome. males have only one x chromosome and females have two. the son of a woman who carries the gene has a 50% chance of being colorblind .the mother is not herself colorblind because the gene is recessive. that means that its effect is suppressed by her matching dominant normal gene .a daughter will not normally be colour blind unless her mother is a carrier and her father is colour blind.
