Monohybrid Punnett squares practice
A classroom resource for 9th-grade students to practice monohybrid Punnett squares, focusing on dominant and recessive alleles, genotype and phenotype, and homozygous and heterozygous traits. Students determine expected ratios, identify homozygous genotypes, and fill in missing key terms through guided questions.

Questions
- In a cross between two heterozygous pea plants (Tt x Tt) for tallness (T = tall, t = short), what is the expected ratio of tall to short offspring?
- Which of the following genotypes are homozygous?
- Fill in the blanks with the correct terms: An organism with two different alleles for a trait is called _, while an organism with two identical alleles is called _.
- Select the correct word for each blank: In a monohybrid cross, the _ is the physical appearance, while the _ is the genetic makeup.
- Put the steps for solving a monohybrid Punnett square in the correct order.
- Match each genotype to its correct phenotype for pea plant height (T = tall, t = short).
- Mark each statement as true or false.
- If a homozygous dominant plant (TT) is crossed with a homozygous recessive plant (tt), what will be the genotype of all offspring?
