Mendel's experiments helped shape the by conducting instead of one, he was able to develop the randomization dihybrid crosses law of inheritance + . When Mendel conducted law of segregation single-trait crosses + to track two traits + law of independent assortment gametogenesis

parent genoty offspring genotypes. We can use this to figure out the probability of 1 How MANY HERITABLE TRAITS ARE USED IN DIHYBRID CROSS? 2. DIHYBRID CROSSES FOLLOW THE SAME RULES AS WHICH OTHER GENETIC DIAGRAM? Dunnet square S 3. How MANY OFFSPRING GENOTYPES ARE WORKED OUT IN A DIHYBRID CROSS? Emmatheteachie 2020 Dihybrid Crosses - Phenotypes LET'S CHECK IF YOU REMEMBER THE RULES FROM CREATING PUNNETT SQUARES! COMPLETE THE SENTENCES: Dominant alleles are represented with a letter. I'M THE BOS! Tt The capital letter is always written Each parent can only pass on allele for each gene. Recessive traits are only shown if both alleles are Now USE THE INFORMATION IN THE PICTURES BELOW TO WORK OUT THE PHENOTYPE FOR EACH GENOTYPE: Dominant traits Recessive traits Bubble fur (B) Spiky fur (b) Yellow body (M Pink body (y) BBYY = BbYy = Bbyy = bbYY= © Ermmotheleachie 2020

Now cross two of the F₁ offspring. Parent 1 Gametes F2 Offspring Parent 2 Gametes 24. What is the phenotypic ratio in the F2 generation? 25. In the dihybrid cross you have considered two traits at a time. Although the number of traits has increased by one, what has happened to the number of possible phenotypes of offspring produced in the F2 generation? ni llit asa2013 bhidydenom sih at Simons 1:11 sabrax gatame
