Two phenotypically normal individuals have an affected child. What can we conclude about the parents?
Correct answer: A. They both carried the disease allele
- A. They both carried the disease allele
- B. They are not the parents of the child
- C. They are affected
- D. No conclusions can be drawn
Explanation
They are phenotypically normal but they carried the allele of specific disease and both are heterozygous and when the gametes combine those alleles might have combined and produced a disease in a child

About Inheritance
Mendel's laws explain segregation, independent assortment and the prediction of genetic ratios using alleles, genotypes and phenotypes. The chapter also covers linked genes, recombination and crossing over during meiosis, then applies pedigree reasoning to X-linked recessive traits, which show different inheritance patterns in males and females.
