#Unit 8. Inheritance Biology

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?
