This exit ticket asks students to complete three parts:
1) Use vocabulary words in sentences. Words include allele, genotype, phenotype, homozygous dominant, homozygous recessive, and heterozygous.
2) Complete a monohybrid cross between a heterozygous green frog and a homozygous recessive blue frog and show the offspring genotypes.
3) Optional dihybrid cross between a heterozygous brown/chunky chinchilla and a lean/white chinchilla, including identifying alleles, writing parent genotypes, performing the cross, and stating the phenotypic ratio.
