Punnett Square Assessment Punnett Square Assessment B1.1D Identify patterns in data and relate them to theoretical models. B4.1c Differentiate between dominant, recessive, codominant, polygenic, and sex-linked traits. B4.1e Determine the genotype and phenotype of monohybrid crosses using a Punnett Square.

Genetics Assessment
	Does not meet expectation 0 pts	Proficient 5 pts	Mastery 10 pts
Inheritance Patterns	Does not meet expectation Is unable to determine inheritance patterns	Proficient Able to identify 2 of the five inheritance patterns	Mastery Able to identify all five inheritance patterns
Layout of Punnett Squares	Does not meet expectation Some parts are mislabeled. Shows confusion about what Punnett square represents.	Proficient	Mastery Can correctly label all parts of a Punnett square.
Create a Punnett square	Does not meet expectation Can not create a Punnett square given the genotypes of parents.	Proficient Given genotypes of parents, can correctly fill out a Punnett square	Mastery Given a two trait Punnett square, student can deduce the genotype and phenotype of parents.
Use of a Punnett square	Does not meet expectation Unable to identify predicted genotypic and phenotypic ratios of offspring in simple dominance traits	Proficient Can correctly identify the predicted genotypic and phenotypic ratios(percents) of offspring in dominant/recessive traits.	Mastery Can correctly identify predicted genotypic and phenotypic ratios of offspring in dominant/recessive, incomplete dominance, sex-linked traits, and codominance.
