Punnett square of a cross between DdAa x Ddaa. Four possible gametes from Ddaa genotype: Da, Da, da, da. Four possible gametes from DdAa genotype: DA, Da, dA, da. Figure 3: Punnett square between DdAa and Ddaa. Based on this information, setup two gene Punnett squares with the following crosses. For each determine the probable genotype ratio and the phenotype ratio and record this next to the Punnett square. BbAa x BBAa FfAa x FfAa TTbb x ttBB GgBB x GgBb

Draw Punnett squares for a monohybrid cross, a sex-linked cross, and a dihybrid cross. Give the expected phenotype and genotype ratios for each.
Shaiju T.
In a dihybrid cross, if two heterozygous individuals for both genes are crossed, what will be the expected phenotypic ratios? (In the following order: dominant for both traits; dominant for the first trait recessive for the second; recessive for the first trait and dominant for the second; recessive for both traits) show your solution using punnet square
