Answer part 3 and part 4. all details are included. aslo show steps when doing the chi sqaure test
the following data set a summarizes f2 numbers from a cross between two, true-breeding drosophila strains (p generation), which differ with respect to two traits. the gene alleles can be dominated or recessive, and autosomal or x-linked.
set a
curved wings, males > 281
wild type, males > 873
red eyes, curved wings, males > 301
red eyes, males > 868
curved wings, females > 575
wild type, females > 1651
1. name the classes and assign genetic symbols to the genes and allies involved. for example, if you suspect an x-linked trait, make it xr+ or xr. if it is autosomal then r and r+.
2. produce a genetic hypothesis about the mode of inheritance of the genes from your data set. for instance, the allele for yellow eyes is x-linked and recessive and the allele for long legs is autosomal dominant. include the expected phenotype ratios in the p, f1, f2 generations. (note: it would be simpler to treat each gene separately, and formulate a genetic hypothesis for each gene).
