Now, let's begin by assuming that the genotype of my unknown plant is this. Okay, so we begin by assuming the genotype is this. And now we want to basically carry out the pundits square experiment. We want to cross our alleles between this genotype and this genotype here. So let's suppose this column are the alleles that came from this parent. So we have upper case T, lower case T. Remember, the law of segregation tells us that during the process of meiosis, when we actually form the sex cell dirtyamides, we have the separation of these homologous chromosomes.
