Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.isnt it because the woman carries this gene ro something? hence 0?
It's actually about playing with probabilities
This condition is expressed when the "gene" is present on both the X chromosomes
And one of those in the case of male as there are no 2 X chromosomes
oh cool
since woman carries she can give it to sons as colour blindness follows criss cross inheritance
@Sephrina is the woman colourblind as well?
Or is it not mentioned?
her father was so i think yeah
cuz she gets the altered x
I mean not exactly
Maybe her mother is normal
One X from father
then she would a carrier no?
Ohh haan I see
Vahi pooch Raha tha like
still chances are there that the woman can give colour blind kids
Is she a carrier of affected
or carrier
carrier
How are you sure
She could be affected as well
true
Say her mother is carrier
it is dependent of situation
And the father is affected
but she will atleast have one
She gets both affected Xa
altered
Yeah at least 1 for sure
Uhh I guess I get it
See
One X from father
Father is not affected
oh wait it is asking affected not carrier
Only one X from mother
ok words confused me
Yeah it's asking for affected
Carriers ka aap bata nahi sakte
there is possibility of being carrier for sure
Unless mother specified ho
but not of being effected
jo nhi hai okkk okk
Non zero hoga yes but kitna hoga vo nahi bata sakte
Yeah
yps
