Using the following Punnett square predict the genotypes and phenotypes of the offspring whose parents are both Bb or have heterozygous black fur homozygous black fur BB heterozygous black fur Bb.
A Punnett Square for a tetrahybrid cross contains 256 boxes with 16 phenotypes and 81 genotypes. A third allele for any one of the traits increases the number of genotypes from 81 to 108. Given this complexity Punnett Squares are not the best method for calculating genotype and phenotype ratios for crosses involving more than one trait.
Crosses Involving One Trait Directions. For the crosses shown in exercises 1-8 draw a Punnett Square in the space provided and write the genotype ratio and phenotype ratio on the indicated lines. Refer to the table below for a description of traits.

Square and the possible gene combinations in the offspring within the square. A completed Punnett square gives the probable outcome of a given cross. However actual results may vary from the probable results especially if only a few organisms are considered.
ONE-FACTOR CROSSES Crosses that involve one trait such as seed coat color are called one-factor crosses. Provide a punnett square to support your answers where indicated. The only difference is that instead of using a capital letter for the dominant trait a lowercase letter for the recessive trait the letters we use are both going to be capital because neither trait dominates the other.
Offspring shows a mix of traits from parents. Punnett Square - is a graphical method proposed by the British geneticist R.
