Overview
I'm working on a biology question and need an explanation and answer to help me learn.
Question 8 (choose 1 of the answers given)If Drosophila has 4 different chromosomes, its diploid number is (4 or 8) The allelic notation shown above demonstrates that the ebony phenotype is (recessive or dominance)
Question9.Using the information in the diagram above, list two autosomal loci that would assort independently. If you crossed two flies heterozygous for the two loci you have chosen, statethe phenotypic ratio you would expect in their offspring.
Question 10.Consider the loci on chromosome 2. Pure breeding wild type flies were crossed to flies with purple eyes and vestigial wings. If the heterozygous offspring of this cross were then used in a test cross, the phenotype of the other test cross parent would be(choose1. Purple eyes orwild type orpurple eyes and vestigial wings orvestigial wing)
Question 11.If this test cross was carried out and 100 offspring produced, state the number of flies expected for each phenotype in the offspring.
