Meiosis and crossing over

Follow one diploid cell through meiosis I and II to four haploid cells. Watch crossing over swap segments.

Open the simulation

What to notice

Crossing over and independent assortment make every gamete genetically unique.

Key relation

2n → 4 cells of n (reductional division) ; combinations = 2ⁿ

Try this

Increase the haploid number and see how fast the number of possible combinations grows.

What you can change

• Haploid number n (for combinations): 1 to 23
• Speed: 0.2 to 2 ×
