Martin Katende Pd: 2-3/Ap Bio LAB 7 Table 7.1: F 1 Generation Data Phenotype and Symbol Females Males Red Eye 611 606 Table 7.2: F1 Generation Data Phenotype and Symbol Females Males Red eye 609 295 White eye 323 Analysis of Results 1. Describe and the name the observed mutation(s). Wild type refers to the phenotype that occurs more often in species. The wild type phenotype seen in these species in both male and female offspring end up with red eyes. The mutant phenotype the phenotype less common is white eyes; it is only seen in some males. The parental generation both had red eyes, and in the F 1 generation the males have white eyes and the females have red eyes. 2. Write a hypothesis that describes the mode of inheritance of the trait(s) you studied. This is your null hypothesis (as described in the Statistical Analysis Section.) There will be an equal number of flies between red and white eyes. 3. Refer a textbook and review punnett squares. In the space below construct two punnett squares to predict the expected results of both the parental and F1 crosses from your null hypothesis. Parental Cross F1 Cross XwY x Xw+ Xw+ Xw+ Xw+ Xw Y Xw+Y x Xw+ Xw Xw+ Xw Xw+ Y Xw+Xw Xw+Xw Xw+Y Xw+Y Xw+Xw+ XwXw+ Xw+Y XwY

4. Refer to the Punnett Squares above. In the box below record the expected ratios for the genotype and phenotypes of the F1 and F2 crosses in the experiment. Expected Genotypic Ration Expected Phenotypic Ratio F1 1:1 1:1 F2 1:1:1:1 1:1:1:1 5. Do the actual results deviate from what was expected? If so, explain how. The actual results do not deviate from the expected results because there was no random chance and less variations. 6. From the results, describe your cross. Is the mutation sex-linked or autosomal? Cross was sex-linked. Is the mutation a dominant or recessive? It is recessive Is the cross monohybrid or dihybrid? A monohybrid cross involving the sex linked white eye allele.
