hey guys..........dont get confused

actually Seepi the option b of your question  is not exactly the same which came in CBSE 1998

that ques had option b as correct ans which is 50% haemophilic colourblind sons and 50% haemophilic sons.

i have checked the sample papers and the ans above is correct.

and one more thing GOOD LUCK to all of u for the D DAY.

and tejas b calm and try this ques again............

Haemophilia and colour blindness both are recessive X-linked traits.They express in males when present in single copy(heterozygous) but in females they express only when present in homozygous condition.

                                 X^hcX^h                     XY           -Parents

                              X^hc , X^h                      X ,Y           -Gametes

                               use punnets square and progenies are

                                        X                Y

                      X^hc           X^hcX                X^hcY                        

                     X^h               X^hX                 X^hY 

RESULTS:

1. 50% sons are colourblinds and haemophilic.

2. 50% sons are haemophilic only.

3. 50% daughters are carrier for colour blindness and haemophilic.

4. 50% daughters are carrier for haemophilic only.
