| Abstract |
The eyeless Nanjo is a mutation that was found in a natural population of Drosophila melanogaster. Genetic analysis of this mutant revealed the following characteristics of this mutation. (1) The homozygous eyelessness is caused by a single recessive mutation which prevents the normal development of compound eyes. (2) An extremely variable morphological eye phenotype was generated by the introduction of a different genetic background to this mutant. (3) The estimated germ line reversion rate was very high. These results suggest that an extremely variable morphological eye phenotype might result from spontaneous somatic excision of some kind of a transposable element.
