Like Father, Like Daughter (Smart Mendel Pea Genetics Simulator)
Source: Stemoto Original
Explore Gregor Mendel's famous pea plant genetics experiments! Combine parent gene cards (Dominant Tall 'T' vs Recessive Short 't'). A smart LED punnett square matrix displays offspring gene probabilities.
Categorisation
Props & Materials Required
- •2x2 Punnett Square matrix board with RFID/NFC tag slots
- •Gene cards (Tall 'T', Short 't', Yellow 'Y', Green 'y')
- •PN532 NFC reader array
- •ESP32 controller board
- •0.96-inch OLED display screen
- •DFPlayer Mini MP3 module + 3W speaker
Step-by-Step Instructions
Insert Parent Gene Cards
Place Father Gene 'Tt' (Hybrid Tall) and Mother Gene 'Tt' into NFC slots.
Smart Punnett Square Matrix Calculation
Controller computes 4 offspring combinations: TT, Tt, Tt, tt.
Observe LED Offspring Ratios
3 boxes light up Green (Tall) and 1 box lights up Blue (Short!).
Genetics Audio Proof
OLED displays 'Genotype Ratio 1:2:1 | Phenotype: 75% Tall, 25% Short!'. Speaker explains Mendel's law of inheritance.
Why It Works & Notes
Like Father, Like Daughter explores inherited family traits (eye color, earlobes, height) and Mendel's pea experiments. Using NFC gene cards on a 2x2 Punnett square board makes genetics probability intuitive.
