In each of the following cases, determine the consequences of a single crossover within the inverted region of a pair of homologous chromosomes with the gene order A B C D in one chromosome and a c b d in the other. There is a two situation of centromere for that gene.
(A) Centromere is not included within the inversion.
(B) Centromere is included within the inversion
Following consequence are resulting are
I - The crossover chromatids consist of a dicentric and an acentric
II- One Cross over product is duplicated for the terminal region contain in A and deficient for the terminal region containing D
III- Both cross over products is monocentric
Following is correct combination for consequence?
