Calculate genotype probabilities:
P(Rr) = 1/4 = 0.25 or 25%
P(rR) = 2/4 = 0.5 or 50%
P(RR) = 1/4 = 0.25 or 25%

What 4 concepts are covered in the Punnett Square Calculator?
- frequency
- number of times a data value occurs
- probability
- the likelihood of an event happening. This value is always between 0 and 1.
P(Event Happening) = Number of Ways the Even Can Happen / Total Number of Outcomes - punnett square
- a square diagram that is used to predict the genotypes of a particular cross or breeding experiment.
- table
- lists of numbers showing the results of a calculation with varying arguments
