Observed phenotypic ratios can differ from expected ratios due to factors such as lethal genotypes, the randomness of fertilization, and the occurrence of mutations.
- one phenotype may have a competitive advantage making individuals more likely to survive, lethal genotypes - random fertilisation may produce different ratios due to chance - mutation may occur
