Tired of the same old Punnett squares worksheets with the same examples used everywhere? Me, too! That’s why I created this worksheet!
⭐ Get these worksheets at a HUGE DISCOUNT in my GENETICS UNIT! ⭐
This worksheet provides simple monohybrid cross Punnett square practice, but with more interesting examples than are usually used. Each page starts with a brief explanation of three traits of an organism, and then gives kids 4 crosses to complete. There are 40 total Punnett squares to do.
For each question, students will:
- Complete a Punnett square.
- Give the genotypic ratio of the offspring.
- Give the phenotypic ratio of the offspring.
Each page of the worksheet is self-contained, so you can assign all 10 pages OR pick and choose the organisms you want to assign. Makes great stations!
And there are three versions provided for easy differentiation!
- Version 1 has students set up and fill in the Punnett squares themselves. (10 pages)
- Version 2 has the sides of the Punnett squares already filled in, and students must complete the boxes. (10 pages)
- Version 3 (easiest) as the Punnett squares are fully completed, and the students answer questions based on the fully completed squares. (10 pages)
The organisms included are (3 traits each):
- Red-Eyed Tree Frogs
- Fly Agaric Mushrooms
- Venus Flytraps
- Rabbits
- Quokkas
- Donkeys
- Lemon Trees
- Sunflowers
- Seals
- Praying Mantis

- NGSS MS-LS3-2: Develop and use a model to describe why asexual reproduction results in offspring with identical genetic information and sexual reproduction results in offspring with genetic variation. Emphasis is on using models such as Punnett squares, diagrams, and simulations to describe the cause and effect relationship of gene transmission from parent(s) to offspring and resulting genetic variation.
