Create a three-generation pedigree demonstrating autosomal recessive inheritance of Spinal Muscular Atrophy Type II (SMA2) caused by mutations in the SMN1 gene. Use standard pedigree symbols: squares for males, circles for females, filled symbols for affected individuals, half-filled symbols for unaffected carriers, and unfilled symbols for unaffected non-carriers. Label each individual by generation and number (I-1, I-2, II-1, etc.) and include the genotype below each individual. Use A for a normal SMN1 allele and a for a disease-causing allele, so affected individuals are aa, carriers are Aa, and unaffected non-carriers are AA. Include at least three offspring in Generation II and at least three offspring in Generation III. Have two unaffected carrier parents (Aa × Aa) in Generation II produce an affected child (aa) in Generation III. Include both males and females in the pedigree. Identify one affected individual in Generation III as the proband using an arrow. Make all individuals living so no deceased symbols are necessary. Title the pedigree “Autosomal Recessive Inheritance of Spinal Muscular Atrophy Type II (SMA2).” Include a legend explaining the symbols and genotypes.
