Phenotype in a punnett square
WebPunnett squares show the genotype of each parent along two sides of a square and all of the potential genotypes of the offspring inside the square. Recall that Mendel often observed a 3 : 1 ratio of dominant to recessive phenotypes (phenotypes included pea color, plant height, flower color, etc.) when he crossed two heterozygous peas. WebThe Punnett Square is a grid-like diagram used to predict the outcome of a particular cross or breeding experiment. This tool helps display all possible gamete allelic combinations in a cross of parents with known genotypes to predict the probability that their offspring will possess certain sets of alleles.
