Following is heterozygote for inversion?
Following some statement given for above abnormality?
A) There is a less probability of a crossover occurring within inversion region and producing an enviable cross over meiotic product.
B) Chromosomes that have engaged in crossing-over separate in the normal fashion, without the creation of a bridge
C) The crossover produces chromatids that contain duplication and a deletion for different parts of the chromosome results non viable gamete
D) Double cross over within inversion loop will be results all viable gamete of parental and recombinant

In individuals heterozygous for a chromosome inversion, the homologous chromosomes form a loop in prophase I of meiosis.
Which of the following is effect of inversion?
A. A dicentric and an acentric chromosome in meiosis I as the chiasmata gets terminated when inversion includes centromere
B. Appearance of deletion and duplication in both the cross over products chromosomes when centromere outside of inversion region
C. All recombinant gamete are non-viable gametes when single crossing over within inverted region; irrespective to paracentric or pericentic inversion
D. Nonviable gametes are usually produced, resulting in a depression in observed recombination frequencies.
Which of the above statements are correct?
