Exact model
A yellow pea seed
- Probability:
- 75%
- Odds:
- 3 to 1
- dBan
- +4.8 dBan
Three of the four equally likely combinations from two plants carrying yellow and green variants produce a yellow seed, because yellow is dominant.
Calculation
p = 3 yellow combinations / 4 combinations = 3/4
Assumptions
This Yy × Yy breeding setup uses a simple one-gene Mendelian model. Peas with other parent genes can have different chances.
