Genetics Practice Problems for Understanding Inheritance Patterns

Test your knowledge of Mendelian genetics with this set of practice problems covering traits such as flower color, eye color, seed shape, cat tails, hair texture, and head shape. Use Punnett squares to predict offspring ratios and reinforce your understanding of dominant and recessive alleles.
