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?

Following some statement are correct?
A) Translocation may be associated with movement of genetic material within the same chromosome
B) A person that is heterozygous for translocation may result in non viability in their zygote
C) A person that is heterozygous for inversion may result in non viability in their recombinant zygote
D) A person that is heterozygous for translocation and lack of crossing over within translocated area result in all viable gametes

Homologous chromosomes pair in prophase I as a following way, if crossing over occur between P and Q gene of homologous chromosome?
Which of the following consequence of above abnormality?
A. Dicentric chromosome visible at anaphase I
B. Results in formation of acentric chromatid
C. Recombinant gamete unable to produced viable progeny due to missing of many gene
D. Resulting recombinant gamete become aneuploid
