Given below is a highly simplified repre-sentaion of the human sex chromosome from a karyotype .The gene a and b could be of :

A

colour blindess and body height

B

attached ear lobe and Rhesus blood group

C

haemophilia and red-green colour blindness

D

phyenylketonuria and haemophilia

Text Solution

Verified by Experts

The correct Answer is:
c
The figure shwo, human sex chromosome with genes a and b so a and b are sexlinked genes, that are inherited through sex chromosomes. The most important characters sex linked inheritance are colourblindness and haemophilia. Both the disorders are due to recessive sex linked gases. the gene for red green colour blindness is located on X chromosomes. The person suffering from this disease is unable to distinguish red and green colours, Haemophilia. also called bleeder's disease, is due to presence of recessive gene on X-chromosomes. the person suffering from this deases have blood which does not clot properly i.e., lacking a factor (plasma throboplastin) which is respeonsible for clotting of blood.
