Messed up in Islamiat, as i hadn't studied much for it.
Wrote the wrong steps of Eid, and didn't add any quotations in most of the questions.

People added so many quotations. Yet got B/C.

I didn't add many, but still got an A.

So it's totally unexpected. Hope for the best. (Y)

In the last question , can we use bloodgroup AB and Bloodgroup AA for the explanation?

The question states that both parents have co-dominant alleles, so both parents should have blood group AB

Isn't it that Ia and Io are also codominant :S
then why do we represent them with I? :S please clear my concept :S

It's the cross section of front view.

 

[princess Anu]

Can somebody just give the points that should be included in the answer to this :
Q Describe the part played by decomposers in a food chain
Q describe how organisms in a food chain form what is known as pyramid of biomass.

How are they co-dominant? Does a person having IaIo have a blood group O?
