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. It is used to predict the possible offspring from a cross, or mating between two parents. Why is a punnett square useful? They represent dominant and recessive genes.
Includes worked examples of dihybrid crosses.
We are using the punnett squares in these instructions to study one trait, but they can also be expanded and used to study more complicated situations in genetics. In our example, we had a 1:2:1 genotypic ratio for homozygous dominant, heterozygous dominant, and homozygous recessive, respectively. Punnett squares are a diagram which biologists use to determine the probability of an offspring having a particular trait. A punnett square is a diagram that was devised by an english geneticist named reginald punnett he was especially interested in why there was a consistent ratio of three to one in his experiments when a punnett square will not be useful.
