A. Organisms heterozygous for inversions and translocations are
viable and able to produce progeny but usually in fewer numbers.
Explain why this is so in general terms.
B. Also, explain how would you distinguish among pericentric
inversions, paracentric inverisons, reciprocal translocations and
non reciprocal translocations as sources of semi-sterility. You
need to consider meiotic figures.
C. How can these chromosome aberrations be used to map genes to
chromosomes or linkage groups. You may use a two-point mapping
system as an...
