Use the diаgrаm оf vаriоus chrоmosomal variations to answer the questions below.  The original chromosomes from two different species are shown in the top left panel.  All other panels are of variations from the wild=type. a. Which of the above variations is associated with FAMILIAL Down syndrome? [1] b. Which of the above variations would lead to a looped chromosome during meiosis I? [2] c. Which of the above variations represents an alloploid? [3] d. Which of the above variations was responsible for the creation of the opsin gene family? [4] e. Which variation is an aneuploid? [5] f. Which of the following lists contains variations that all lead to non-viable gametes/ embryos? [6] g. Which variation is associated with pseudo-dominance? [7] h. Which variation is a pericentric inversion? [8] i. Two double stranded breaks occur.  One is on one member of chromosome pair and one is on the other member of the pair.  The breaks are in different places on each chromosome.  Which two variations may result when the chromosomes are repaired? [9] j.  Which variation is an autoploid? [10]

Arаbinоse is а sugаr that can be used by E. cоli.  Twо genes, AraA and AraB, encode proteins that bring arabinose into the cell and convert it into glucose.  These genes are part of an operon that turns on only in the presence of arabinose.  The table shows this wild-type response and the response of a mutant strain of E. coli that has been isolated.  Also, shown is the response in pseudo-diploid bacteria with the indicated genotype.  Use this information to answer the questions below. a. Based on the information given in the text above, is this an inducible or repressible system? [1] b. When only considering line number __ in the table (do not consider the pseudo diploid result), which of the following hypotheses could explain this mutation (select the list that contains the appropriate numbers)? [2] 1. Loss of an activator protein     2. Loss of a repressor protein     3. Gain of an activator protein     4. Gain of a repressor protein     5. Mutation in a repressor binding site     6. Mutation in an activator biding site c. Now, take a look at line __.  Is this result indicative of trans or cis regulation? [3]
