Chromosomal localization of autosomal mutations inDrosophila nasuta nasuta andDrosophila nasuta albomicans

Abstract: By analyzing the progeny of crosses involving brown eye mutants and the wild types in two members of Drosophila nasuta subgroup namely D. n. nasuta and D. n. albomicans we could show that the mutant gene is recessive, located in the chromosome 2 and the alleles of this gene are present at different loci. A study of fitness in the eye color mutants in comparison with the wild types revealed that D. n. nasuta mutant has higher viability at both 25 ± 1 • C and ambient temperatures; while D. n. albomicans mutant h… Show more

“…The brown mutation in D. n. nasuta and D. n. albomicans is not isolocus and therefore reciprocal crosses conducted between brown of D. n. nasuta and brown of D. n. albomicans yields only wild-type phenotype (Ashadevi et al 2005). Hence, the competition between conspecific and heterospecific sperm and the pattern of sperm precedence in the F 1 hybrids could not be included for the present study and thus we focussed only on intraspecific sperm competition involving these two subspecies.…”
