Compare observations of Punnett squares and describe the pattern you notice
Free printable Grade 7 science worksheet for "Compare observations of Punnett squares and describe the pattern you notice" — practice genetics and biotechnology. No-prep, print or assign online.
Middle school students compare observations of Punnett squares and describe the genetic patterns they notice — dominant and recessive inheritance, ratios, and predicted phenotypes — building core genetics literacy. Teachers can use this hard worksheet as a consolidation task after modeling Punnett square construction, helping students move from mechanics to pattern recognition. It fits within the Life Science strand on genetics and biotechnology.
Learning objectives
- Compare Punnett square outcomes for different crosses and describe the inheritance pattern
