Reginald crundall punnett, a mathematician, came up with these in 1905, long after mendel's experiments. 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. Find out why inheritance of dominant and recessive alleles produces the characteristics that make every the punnett square below shows the expected genotypes of the offspring of parent pea plants that both have the genotype rr.
Each box in a punnett square represents a possible fertilization event, or offspring genotype, arising from two although punnett squares are useful in many contexts, they cannot accurately depict complex genetic inheritance.

Making punnett squares is a good way to get started understanding the fundamental concepts of genetics. They are useful as they can predict the genetic probability of a particular phenotype arising in a couple's offspring. It can also be used to predict the most likely phenotype of how the trait will be expressed. Let's take a look at how punnet squares work using the.
