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?

Trisomy 18 is one of the most common trisomies observed in human populations. You prepare DNA samples from two unrelated infants, both with trisomy 18, and from their parents. You then type the infants and their parents for four SSRs distributed along chromosome 18:
