Chromosome Pairing Simulator

G7 Cycle 1 Week 5 - Introduction to Heredity

How to Use This Simulation

Keyboard: Space/Enter = start/pause · R = reset · Esc = pause

Human Karyotype 23 Pairs = 46 Chromosomes

From Mom (Maternal)

From Dad (Paternal)

Gene Information

Total Chromosomes in Every Cell

1. How many chromosomes did you inherit from each parent?

2. If mom has brown eyes (Bb) and dad has blue eyes (bb), what alleles might be on chromosome pair 15?

3. Why do siblings look different if they have the same parents?

4. What makes pair 23 special compared to other pairs?
