WebAfter you get good at this you should never miss a genetic question involving the cross of two organisms. BABY STEPS: 1. determine the genotypes of the parent organisms. 2. write down your "cross" (mating) 3. draw a p-square. 4. "split" the letters of the genotype for each parent & put them "outside" the p-square. WebThe genotype of an organism is often expressed using letters. The visible expression of the genotype is called an organism's phenotype. Alleles are not created equal. Some alleles mask the presence of others. Alleles that are masked by others are called recessive alleles. small flower drawing outline
