Question

Which of the following statements accurately describe the disorder being tracked in the pedigree shown here? The autosomal recessive pedigree shows the list to find out an autosomal recessive disorder.The pedigree shows that the parents are carriers for an autosomal recessive disorder. An affected parent (aa) on cross with an unaffected A_ (one allele unknown) on step 1 to form A_, Aa, Aa and A_ in step 2. The alleles in step 3 are Aa, Aa, A_, and A_. Alleles in the final step 4 are aa, aa and A_. Key: aa equals affected, Aa equals carrier (unaffected), AA equals unaffected and A_ equals unaffected (one allele unknown). The text underneath reads:Unaffected parents can produce children who are affected. Heterozygotes (Aa) are unaffected. Both males and females may be affected with equal frequency. Check All That Apply Unaffected parents have children that are affected.Unaffected parents have children that are affected. The individuals that are heterozygotes are unaffected.The individuals that are heterozygotes are unaffected. Both male and females are affected by the disorder.Both male and females are affected by the disorder. The inheritance pattern shown in the pedigree is autosomal dominant.The inheritance pattern shown in the pedigree is autosomal dominant. Heterozygotes are carriers.
