Font Styles White-eyed fly x Red-eyed fly Number of Offspring Phenotype of Offspring red eyes (normal) 57 white eyes (mutant) 0. Bar-eyed fly x Round-eyed fly Phenotype of Offspring Number of Offspring round eyes (normal) bar eyes (mutant) 68 Analyze and Conclude Answer the following questions on a separate sheef of paper. 1. Is the white-eyed phenotype caused by a dominant allele or by a recessive allele? Is the bar-eyed phenotype caused by a dominant allele or by a necessive allele? Explain how you know. 2. Write the genotype for each mutant fruit fly. Identify what symbols stand for. 3. Construct a Punnett square for each cross that the gencticist set up. (You can assume that the normal flies are homozygous.) How do the geneticist's results compare to those predicted by the Punnett squares? 4. For each cross, what results would you expect if the geneticist crossed the F1 offspring? Construct a Punnett square to show the results of each cross. Also for each cross, calculate the probability of getting offspring with the mutant phenotype. your genetic O Peorson Edscotion, Inc., publishing as Pourson Prentice Huk. All riits reservel.
