An individual is having an inversion in heterozygous condition. The regions on normal chromosome are marked as A, B, C, D, E, F, G while the chromosome having inversion has the regions as a, b, e, d, c, f, g. The diagram given below shows pairing of these two homologous chromosomes during meiosis and the site of a crossing over is indicated:
The following statements are given to describe the inversion and the consequence of crossing over shown in the above diagram:
A. This is a paracentric inversion
B. This will generate a dicentric and an acentric chromosome following separation of chromosomes after crossing over
C. This will generate two recombinant chromosomes with deletion and other parental chrmosome following separation of chromosomes after crossing over
D. 50 % gametes will be non viable due to deletion or duplication of chromatids
E. The gametes having recombinant chromatid or parental inversion chromatids will be non-viable

A female fly, full of fertilized eggs, is swept by high winds to an island far out to sea. She is the first fly to arrive on this island, and the only fly to arrive in this way. Thousands of years later, her numerous offspring occupy the island, but none of them resembles her. There are, instead, several species each of which eats only a certain type of food. None of the species can fly, for their flight wings are absent, and their balancing organs (i.e., halteres) are now used in courtship displays. The male members of each species bear modified halteres that are unique in appearance to their species. Females bear vestigial halteres. The ranges of all of the daughter species overlap.In each fly species, the entire body segment that gave rise to the original flight wings is missing. The mutation(s) that led to the flightless condition could have
