Dihybrid Crosses - Problem 1 I IHINK WE WERE IN THE BATH TOR TO0 LONGI WE'LL STICK WITH PEAS FOR THE FIRST PROBLEMI The allele for round peos (R) is dominant over the allele for wrinkled peas. The ollele for yellow peos (Y) is dominant 80 over the allele for green peas. Parent 1 is wrinkled and heterozygous for pea color. Parent 2 is heterozygous for smoothness and homozygous recessive for pea color. Work out the possible offspring genotypes and phenotyYpes and give the expected probability of each phenotype. STEP 1) WORK OUT THE PARENT GENOTYPES AND GAMETE ALLELES. FOIL reminder! Parent 1 genotype: Oute First BbYy Parent 1 gametes: Parent 2 genotype: nner Parent 2 gametes: Lost O Emmatheteachie 2020 Dihybrid Crosses - Problem 1 STEP 2) PUT THE PARENT ALLELES IN EACH GAMETE ACROSS THE TOP AND SIDE OF THE GRID. STEP 3) READ ACROSS & DOWN TO WORK OUT OFFSPRING GENOTYPE. STEP 4) FIGURE OUT THE OFFSPRING PHENO- TYPES (& IN THIS VERSION YOU CAN DRAG THE RIGHT PICTURE INTO EACH SQUARE!) WORK OUT THE PROBABILITY OF EACH OFFSPRING PHENOTYPE. STEP 5 Round & yellow = /16 Round & green = /16 Wrinkled & yellow = /16 Wrinkled & green = /16 © Emmatheteachie 2020
