Patterns of Corn ear inheritance 
Patterns of Inheritance/Organism Design
Students work on corn inheritance to prove their familiarity in understanding of Mendelian genetics. Students will demonstrate understanding through visual description of phenotypes, explanation of inheritance, and show the sgregation of traits fits into mendelian ration

Understanding Crosses

Does not meet minimum Expectation

Using parental cross cards, student failed to identify type of cross; fail to identify phenotypes
Meet minimum Expectation

Abled to identify cross but failed to identify phenotype of parents
Meet the expectation

Both cross and phenotype identification were correct
Above expectation

Both cross and phenotype identification were correct.

Includes a discussion of expected outcomes
Phenotype and genotype of F1

Does not meet minimum Expectation

Failed to decide
Meet minimum Expectation

Genotype was correct but phenotype was wrong
Meet the expectation

Both phenotype and genotype were correct
Above expectation

Both phenotype and genotype were correct and include a cross chart
Monohybrid cross

Does not meet minimum Expectation

Student was given an F2 ear of corn. Student was asked to give an imaginary genotype of the traits and show if the segregation follow monohybrid ration

Student failed to assign correct genotypes and could not analyze Chi-squre
Meet minimum Expectation

Student was given an F2 ear of corn. Student was asked to give an imaginary genotype of the traits and show if the segregation follow monohybrid ratio.

Genotype assignment was correct but failed in Chi-square analysis
Meet the expectation
