Saying that normal S and s is the gene for sickle cell anemia. The woman is heterozygous for the genotype Ss, while the males are ss.
Laying With the square:
____S____s
s___Ss___ss
s___Ss___ss
50% of children suffering from sickle cell anemia
Edit: Nita, is wrong. Heterozygotes are usually asymptomatic. Homozygous treatments are vulnerable to numerous complications, including death, and are probably multiple transfusions throughout their life cycle and require the life expectancy, but are
Your question asker wanted to have a congenital defect. Sickle cell anemia, which are heterozygous only.
The sickle-cell anemia gene is found in the autosomes, and is a recessive gene, as you say. This gene is lethal in the homozygous state. A normal person, man or woman must be homozygous normal gene.Only heterozygotes suffer from the disease.
The issue of women is not a carrier or heterozygous and normal.
If both are heterozygous for this gene, the chances for normal children by 25%, 50% of sickle-cell heterozygotes and 25% of children die due to severe anemia.
Nita is bad, but Jaibi is absolutely correct.
If S is recessive () and S defect is the dominant allele (normal) allele, then the SS parental genotypes (heterozygous) and SS (homozygous recessive), and if you have a child, 50% ss (normal, but we do) and 50 % ss (victim).
