I have been following you since I was grade 11, Now I am Postdoctorate and I even can't imagine going to class without listening You... Hats OFF... You are God Gifted and your Teaching method is Intuitive. You are Not You... You speak Words of Heaven
Wow, thank you!
@@DoctorNajeeb sir
In case of AB blood group there is also possiblity that the chromosome which you have received from father have gene for. AB blood group and another chromosome which you have received from you mother have non functional gene ( i.e O blood group)
@@DoctorNajeeb sir I am not intelligent student
But sir this thought comes in my mind
So
I request your good self
Plz clear my this confusion
That will b your most kindness ❤️
@@nasreenahassan1765 each locus will have one gene either A or B . It can't have both AB
@@33.md.ashikurrahman74 see Aa gene give one parent and Bb give another parent , form cis Position AB , ab . And get AB blood group.
