Vedclass · Answer

(D) Sickle cell anaemia is an autosomal recessive disorder. Let the normal allele be $Hb^A$ and the sickle cell allele be $Hb^S$.Both parents are carriers,meaning their genotype is $Hb^A Hb^S$.When a cross is performed between two carriers $(Hb^A Hb^S 	imes Hb^A Hb^S)$,the resulting offspring genotypes are:$25\% Hb^A Hb^A$ (Normal),$50\% Hb^A Hb^S$ (Carrier),$25\% Hb^S Hb^S$ (Affected/Anaemic).Therefore,the probability of having an anaemic child is $25\%$.

$A$ couple,both carriers for the gene of sickle cell anaemia,are planning to get married. What are the chances of them having an anaemic child (in $\%$)?
