RUFF! MY EARS ARE DOMINANT! Dihybrid Crosses - Problem 2 THIS ONE ISN'T REAL (DOG EARS / COLORING ISN'T CONTROLLED BY A SINGLE GENE!) The allele for floppy ears (F) is dominant over the allele for pointed ears. The allele for grey markings (G) is dominant over the allele for brown markings. STEP 2 Parent 1 is homozygous recessive for ear type and homozygous dominant for fur markings. Parent 2 is heterozygous for both traits. Work out the possible offspring genotypes and phenotypes and give the expected probability of each phenotype. WORK OUT THE PARENT GENOTYPES AND GAMETE ALLELES. FOIL reminder!
