A variety of peach, Desert Peach, has a uniformly skin that is mainly with random blotches of pink. The gene required for called and the are located the same chromosome, chromosome A spontaneous form this old Man, produces fruit the same white and pink coloring with where the pink. Which one of the following statements consistent with the appearance of these two peaches? Solution 6. A spontaneous mutant can be either insertional of nucleotides or chromosomal rearrangements on a chromosome. As the old man mutant has fuzziness but only in the pink regions, it might be due to rearrangement of the fuzziness gene ahead of the pink colour gene due to which it is expressed in the pink region. 7. When this DNA binding protein is expressed in the old man mutant, the fuzziness is gone, which means that expression of fuzziness gene is repressed. So it might be this DNA binding protein is repressing the expression of fuzziness gene..
