1.	In pericentric inversion, the inversion loop involves __________ strands.(a) 1(b) 2(c) 3(d) 4The question was asked at a job interview.My doubt stems from Chromosomal Abnormality : Inversion in portion Chromosomal Basis of Inheritance of Cytogenetics
Answer» Right option is (d) 4 The best I can EXPLAIN: In PERICENTRIC INVERSION there will be 4 strands in the inversion LOOP although only 2 will undergo recombination to give the recombination products. This is because the sister chromatids are bound by the centromere.
