Question

Which of the following represents the chances of progeny in sicke cell anaemia if the man is normal (AA) and the woman is sufferer?​

Answer 1

Sickle Cell Trait (or Sickle Trait)

Answer 2

Progenies in SICKLE CELL ANEMIA:

• Sickle Cell Anemia is an autosomal recessive disorder.

• As per question, man is normal (AA) and woman is suffering $A_{s}A_{s}$.

• So, let's create a Punnett Square as attached in the image :

All the progenies will have genotype as follows:

• $AA_{s}$ : 4 progenies

But since sickle cell anemia is an AUTOSOMAL RECESSIVE DISORDER,

• The progenies will be carrier of Sickle Cell Anemia.

• In that case, they will have SICKLE CELL TRAIT.
