none of them will b normal.
after cross breedn we av nly
AS,AS,SS,SS.
and since a normal gene takes AA,odas are sickle cells nd carriers
So, if the answer is D
Does it now mean that all AS are abnormal?
This question is something else o
Sickle cell trait ( also known as being a carrier...AS ) occurs when a person has one gene for sickle hemoglobin and one gene for normal hemoglobin.
Although,most people who are AS carrier doesn't show any health problems
People who carry sickle cell AS will not develop sickle cell disease SS, but may be at risk of having a child with sickle cell disease and may occasionally need to take precautions to stop them becoming unwell.
So definitely AS doesn't show health problems but they are not normal
A normal Gene cell is AA
The option is wrong... They're have two normal kids but are carriers (AS) and two sickle kids (SS). Option B is most appropriate
