alt , you will use the observed solution colour change due to phenolphthalein (colourless e endpoint) to indicate the completion of each reaction. Due to the colours of the juices you will be studying, the expected colour change of colourless to pink may not be observed. For each juice, state the colour change that you will likely observe at the endpoint. Grapefruit juice Orange juice Lemon juice 3. The indicator that will be used in Part 2 is bromophenol blue....

A function that takes in as input the colour of a car, and returns the number of cars of that colour present in a file that contains the colour of cars parked in a lot. Create the file, and put in colour of cars (the number of entries doesn't matter, but make sure there is repetition) E.g Blue Red Blue Green Black Red ............. and so on

BR In harebells, wild type flower colour is blue. You have found three white petalled mutants which are homozygous pure breeding strains. When you cross each of these with a wild type pure breeding strain, all the offspring have blue flowers, and the F2 gives a 3:1 ratio of blue to white. When you cross two of the white mutants together, the Fl generation are all blue! When you self the FI, the F2 generation gives a ratio of 9...

2.(2) In Drosophila, black body colour is due to a recessive allele (b) and normal body colour is due to a dominant, wild-type allele (b+). If black bodied females are crossed to pure wild-type males, what phenotypic and genotypic ratios are expected if the F2 males are backcrossed to black-bodied parental females? Show your work.
