Punnett square with 3 traits.

Figure 3.15.1 3.15. 1: The Punnett square of a cross between two purple flowers ( Bb ). A Punnett square can be used to calculate what percentage of offspring will have a certain trait. To create a Punnett square, perform the following steps: Take the factors from the first parent and place them at the top of the square ( B and b ). A test cross is a cross between the unknown (?) genotype and a homozygous (?) dominant, recessive. In a dihybrid cross, the F2 will have nine genotypes, but only four phenotypes because the (?) genes cause the (?) traits to mask the (?) traits. heterozygous, dominant, recessive. A cross between plants which differ in only two traits is a (?) cross. Table 6.1.1 6.1. 1: Phenotypic classes expected in monohybrid and dihybrid crosses for two seed traits in pea. The 9:3:3:1 phenotypic ratio that we calculated using the product rule can also be obtained using Punnett Square (Figure 6.1.4 6.1. 4 ). This is known as the law of segregation. A Punnett square can be used to predict genotypes (allele combinations) and phenotypes (observable traits) of offspring from genetic crosses. A test cross can be used to determine whether an organism with a dominant phenotype is homozygous or heterozygous. Below is a sampling of Punnett Square problems that you will be expected to solve. In order to do this, you will also have to understand the meaning of the terms below. Genotype: The letters that make up the individual. E.g. TT or Tt Phenotype: The physical characteristics of the particular trait. E.g.
