That's why i've put together this detailed guide to punnett square values. A cross in which one characteristic is tracked is a monohybrid cross. We know that each individual can give only one of it's two alleles. Learn how to use punnett squares to calculate probabilities of different phenotypes. 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 the genotypes of a particular cross or breeding experiment. In this example, both parents are heterozygous for flowercolor ( bb ). The offspring of a monohybrid cross is called monohybrids. In its simplest form, the punnett square consists of a square divided into four quadrants. Study the drawings for the sake of understanding then memorize the logic behind every ratio. This video tutorial helps explain the basics of punnett square.
