#2 a) Table 1 shows the results that Thomas Hunt Morgan got when his lab crossed Red-eyed fruit flies with White-eyed fruit flies. The crossing of the parental generation and F1 generation fruit flies looked like textbook Mendelian inheritance, but if the phenotypes were looked at with reference to the sex of the fruit fly, the phenotypic ratios were different from standard Mendelian ratios.

Step 1
T.H. Morgan with the help of this experiment demonstrated the X-linked pattern of inheritance. When a particular gene is present on the autosomes of male and female then in next generation they will produce an expected phenotype and ratio as Mendelian inheritance. When the genes are present on sex chromosomes then the inheritance is deviated from the typical Mendelian ratio. T.H. Morgan demonstrated this deviation from Mendelian ration through this experiment.
