Solution
The correct option is A Haemophilia and red and green colour blindness
The given picture shows X and Y chromosomes. The larger is X chromosome and smaller is the Y chromosome. Genes for haemophilia and red and green colour blindness are exclusively present on the X chromosome as these two are the X-linked disorders. Phenylketonuria and Rhesus blood group are present on the autosomes and hence "A" and "B" can not show the genes for these traits. Correct answer is option C.
