Mendelian Genetics Simulation
Exploring Inheritance with Beads and Punnett Squares
This simulation demonstrates Mendelian inheritance patterns. Select alleles for parent organisms, then see how they combine in offspring using both bead models and Punnett squares.
Parent 1 Alleles
Parent 2 Alleles
Observation:
Select alleles for both parents by clicking on the beads, then click "Perform Cross" to see the possible offspring combinations.
Mendelian Genetics Principles
1. Law of Segregation:
Organisms inherit two alleles for each trait (one from each parent). These alleles separate during gamete formation.
2. Law of Independent Assortment:
Genes for different traits are inherited independently of one another (for genes on different chromosomes).
3. Dominance:
Some alleles are dominant and mask the expression of recessive alleles. Dominant traits are expressed when at least one dominant allele is present.
