The Punnett Square, named after the British geneticist Reginald C. Punnett, is a tool that allows us, based on the genetic information of two parental organisms, to predict the genotypes and phenotypes of their offspring. With the help of the Punnett Square Generator that we present here, you will be able to take advantage of this wonderful genetic analysis tool.
To use the online Punnett Square Generator you must follow these steps:
After explaining how to use the punnet square calculator, below we present the basic theoretical concepts related to the Punnett Square, so that you have all the necessary elements to understand in depth the great potential that this wonderful genetic prediction tool offers us.
The set of observable characteristics of an individual, taking into account its morphology, physiology and behavior, is called the phenotype. An individual’s phenotype not only refers to observable characteristics, but also groups molecules and structures such as RNA and proteins produced as encoded by genes; which is called the “molecular phenotype”.
This tool helps display all possible gamete allelic combinations in a cross of parents with known genotypes to predict the probability that their offspring will possess certain sets of alleles.
In the Punnett square, uppercase letters are used to represent dominant alleles and lowercase letters to represent recessive alleles. Thanks to this, it is very easy to observe how the alleles are inherited or transmitted to the offspring of the parents.
To make Punnett squares you must follow these steps:
We recommend you practice with the punnett square calculator so that you fully understand the steps explained above.
