How Traits Are Inherited
Learn how traits pass from parents to children through genetic inheritance. Review dominant, recessive, X-linked, mitochondrial and other patterns with Punnett squares and pedigree examples.
Punnett squares
Use allele combinations to estimate possible genotypes and trait probabilities.
Patterns of inheritance
Compare autosomal, sex-linked, mitochondrial, codominant and incomplete dominance patterns.
Pedigree charts
Learn how family diagrams can help identify patterns of inherited traits.
