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.

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

1

Insert Parent Gene Cards

Place Father Gene 'Tt' (Hybrid Tall) and Mother Gene 'Tt' into NFC slots.

2

Smart Punnett Square Matrix Calculation

Controller computes 4 offspring combinations: TT, Tt, Tt, tt.

3

Observe LED Offspring Ratios

3 boxes light up Green (Tall) and 1 box lights up Blue (Short!).

4

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.
