ELL Genetics Vocab is a Grade 9 science worksheet that builds foundational genetics vocabulary through 12 questions: 11 multiple-choice items and one multiple-select item. Students identify alleles, genes, dominant traits, genotypes, and phenotypes, then classify homozygous and heterozygous genotypes using examples such as AA, Aa, and aa. The worksheet also asks students to distinguish observable traits from genetic combinations and determine which flower genotypes produce dominant purple flowers or recessive white flowers. Its final questions require students to select both genotypes associated with a dominant trait and the single genotype associated with a recessive trait. This free printable worksheet includes a complete answer key and is designed for Grade 9 science practice, review, or a vocabulary-focused check for understanding.

This Grade 9 science worksheet uses 11 multiple-choice questions and one multiple-select question to practice genetics vocabulary and classification. Students distinguish genes from alleles, genotypes from phenotypes, and homozygous from heterozygous combinations, then apply those terms to AA, Aa, and aa flower examples.
Introduce the vocabulary by having students connect each term to its definition or example, such as an allele as a version of a gene and a genotype as an allele combination. Then use the AA, Aa, and aa items to model how genotype labels relate to dominant purple flowers and recessive white flowers before students complete the multiple-select question independently.
Students may confuse an allele, which is a version of a gene, with a gene, which occupies a specific chromosome location. They may also reverse genotype and phenotype, misidentify Aa as homozygous, or select only PP for the dominant purple-flower trait instead of recognizing both PP and Pp; the recessive white-flower genotype is pp.
The worksheet is available as a printable PDF and as a digital quiz on Wayground, and it includes a complete answer key for all 12 items. Printable submissions can be graded by scanning student work with the Wayground for Teachers app. The PDF option also supports schools that want to reduce screen time.
In the worksheet’s Advanced Settings, adjust font spacing or choose a larger font size to make the vocabulary definitions, genotype examples, and answer choices easier to read. You can also enable a dyslexia-friendly font or translate the worksheet into another language to support access to terms such as genotype, phenotype, homozygous, and heterozygous.
