A punnett square is a diagram that was devised by an english geneticist named reginald punnett in the first half of the 20th century in order to determine the statistical likelihood of each possible genotype of the offspring of two parents. The punnett square is a square diagram that is used to predict an outcome of a particular cross or breeding experiment. Creating a punnett square requires knowledge of the genetic composition of the parents. Making punnett squares is a good way to get started understanding the fundamental concepts of genetics. We know that each individual can give only one of it's two alleles. It can also be used to predict the most likely phenotype of how the trait will be expressed. Using a punnett square properly will enable you to figure out potential offspring for any possible morphs that are genetically homozygous will always produce offspring that are morphs, which is why they the punnett square is an extremely useful tool for understanding odds and probabilities for. What a punnett square does is that it tells you, given the genotypes of the parents, what alleles are likely to be expressed in the offspring. Genetics science of heredity punnett squares are a useful tool for predicting what the offspring will look like when mating. Some of the terminology you'll come across when dealing with genetics can be confusing, so we'll start by defining some terms and then put them all together to see how they relate. All possible genotypes for the haploid female gametes are listed. It is used to predict the possible offspring from a cross, or mating between an example of a punnett square ( figure below ) shows the results of a cross between two purple flowers that each have one dominant factor and one. Punnett, who devised conclusions and analysis.
