Inversion Problems: An individual is heterozygous for an inversion: ADCBEFG HI, and during gamete formation there is a crossing over event between C and B. Draw chromosome structure pre and post meiosis. Be sure to label the chromatids/chromosomes with the appropriate sequence of genes. Label mutant and wild type chromatids/chromosomes, viable and non-viable gametes. Circle and identify the mutations in the non-viable gametes inuerston If an individual is heterozygous for an inversion, ABC DGFEHI, and a crossing over event occurred...

Which of the statements are true of both first- and second-division nondisjunction? Select all that apply. a. Homologous chromosomes fail to separate. b. Gametes are produced with extra chromosomes. c. Half of the gametes produced are wild-type, whereas half are mutated. d. Sister chromatids fail to separate. e. Gametes are produced with missing chromosomes.

Gametes produced in a paracentric inversion heterozygote WITHOUT crossing over are: a. two gametes with deletions and/or duplications and two normal gametes b. one normal gamete, two with deletions and/or duplications and one with the inversion c. two gametes with the inversion and two normal gametes d. two gametes with the inversion and two with the deletion and/or duplications e. No normal gametes

What structure might be visible in a reciprocal translocation HOMOZYGOTE during meiosis? a. stem loop b. cross-shaped figure c. inversion loop d. breakage-fusion bridge e. none of the above I Know that when it is a reciprocal translocation heterozygote a cross shaped figure is formed, but I can't find any information on what forms if it is reciprocal translocation homozygote. Any help would be appreciated. Thank You.
