This video will show how to set up and solve everyone's favorite 16 square punnett square. If a person has a genotype of bb for eye color where brown is dominant to green, what 3 punnett squares method used to visually analyze crosses and predict offspring or identify parent genotypes. Punnett squares punnett squares are a useful tool for predicting what the offspring will look like when mating plants or animals. Reginald crundall punnett, a mathematician, came up with these in 1905, long after mendel's experiments.
These two traits are independent of each other. Cross a heterozygous plant with a homozygous short plant. He gives a number of examples of monohybrid crosses and one example of a dihybrid cross. Creating a punnett square and using it to determine traits of offspring is called performing a cross. Tall is dominant and short is recessive in pea plants.
