Question

question 2
george is a carrier for sickle cell anemia, an autosomal recessive disorder, while georgette is affected. what are the odds that their future child will be a carrier?
a 1/2
b 1/8
c 1/3
d 3/8
e 3/4
f 1/6
g 0
h 2/3
i 1/4

Explanation:

Step1: Determine genotypes

Let \( S \) represent the normal allele and \( s \) represent the sickle - cell allele. Since sickle - cell anemia is autosomal recessive, George (a carrier) has the genotype \( Ss \), and Georgette (affected) has the genotype \( ss \).

Step2: Use Punnett square

	\( S \)	\( s \)
\( s \)	\( Ss \)	\( ss \)

The possible genotypes of their children are \( Ss \) (carrier) and \( ss \) (affected). There are 2 out of 4 possible genotypes that are \( Ss \).

Answer:

A. \( 1/2 \)
