The chromosome has been broken at two points, and the segment between them has been inverted. What will be affects of this inversion however, person is heterozygous this abnormality?

#Unit 8. Inheritance Biology

  1. It may change the relative lengths of the two arms of the chromosome

  2. This stretches the dicentric chromatid across the center of the nucleus, forming a structure called a dicentric bridge

  3. Two of four gametes contain recombinant chromosomes that are missing some genes however no duplication of gene; these gametes will not produce viable offspring

  4. Recombination is not reduced within a inverted region comparatively normal
