why is a punnett square called a punnett square
Punnett square
The Punnett square is a diagram that is used to predict an outcome of a particular cross or breeding experiment . It is named after Reginald C. Punnett , who devised the approach . The diagram is used by biologists to determine the probability of an offspring having a particular genotype . The Punnett square is a tabular summary of possible combinations of maternal alleles with paternal alleles . These tables can be used to examine the genotypic outcome probabilities of the offspring of a single trait ( allele ) , or when crossing multiple traits from the parents . The Punnett Square is a visual representation of Mendelian inheritance . It is important to understand the terms `` heterozygous '' , `` homozygous '' , `` double heterozygote '' ( or homozygote ) , `` dominant allele '' and `` recessive allele '' when using the Punnett square method . For multiple traits , using the `` forked - line method '' is typically much easier than the Punnett square . Phenotypes may be predicted with at least better - than - chance accuracy using a Punnett square , but the phenotype that may appear in the presence of a given genotype can in some instances be influenced by many other factors , as when polygenic inheritance and / or epigenetics are at work . It is a square with 2 lines that look like a window with letters .
