9 Best Free Online Punnett Square Calculator Websites

Check out these best free online Punnett square calculator websites. Punnett square is a way to predict the probability of different traits in an offspring. This allows you to visualize the potential outcomes of a genetic cross. It can help you under the inheritance pattern of the genes. However, creating a Punnett square can be a hassle that also takes time. Instead, a Punnett square calculator can do the same within seconds.

This post covers 9 free websites where you can generate Punnett squares online. These calculators can draw the Punnett squares based on the parent’s genotype. You just have to provide the genotype of each parent. Some of these calculators allow you to include multiple cross traits to make a comprehensive Punnett square. Along with Punnett square, you also frequency table that visualizes the probability of different genetic traits being passed on to future generations.

My Favorite Online Punnett Square Calculator

SciencePrimer.com is my favorite website on this list to calculate Punnett square online. The calculator on this website can draw a Punnett square for up to 5 cross traits. It also shows frequencies showing the number of selected traits, total squares, and unique allele combinations. It also generates a table covering each genotype combination with its count and percentage.

SciencePrimer.com

SciencePrimer.com offers a free online Punnett Square calculator. This calculator shows the genotypes two individuals can produce when crossed. The calculator lets you pick the number of traits in the cross. You can go with 1, 2, 3, 4, or 5 trails. The more the number of traits, the bigger the Punnett square. After selecting the number of traits, you can also view the frequencies to get an overview of genotypes with count and percentage. Below that, it draws the Punnett square for the same. You can edit the Alleles of both parents and pick the dominant allele for each trait.
