Genetics of Minute Locus in Drosophila Melanogaster
Minutes are a class of dominant mutants that are characterized by their recessive lethality, increased developmental time, smaller body with short fine bristles in the heterozygotes and with varying degrees of reduced survival and fertility (Lindsley et al., 1972). This class of mutants was first described by Bridges and Morgan (1923) and as a group presents many interesting genetical features. These include: autonomy of the rate of the mitotic division in some Minutes (Morata and Ripoll, 1975), induction of non-disjunction in the X-chromosome (Miklos, 1970), cell autonomy of some Minutes in chaetae differentiation, and cell lethality in genetic mosaics (Stern and Tokunaga, 1971), and their high rate of induction by ethylmethanesulfonate (Huang and Baker, 1976).
