Which of the following statements about chromosomal inversions is NOT true? Group of answer choices An inversion can break a gene into two parts and separate each to different locations. The expression of the gene may be altered due to positional effects. The individual organisms have neither lost nor gained any genetic material. Individuals heterozygous for inversions may end up producing abnormal gametes. Inversions have no effect on meiosis

9. Inversions can have an effect on the phenotype of the organism when: A) the inversion is paracentric. B) the inversion's breakpoints do not alter any of the inverted segments' gene sequences. C) the inversion is pericentric. D) the transcribed region of a gene spans one or more of the inversion's breakpoints.

Pick the statement about chromosome structure that is FALSE. Gene duplications provide an explanation for the origin of gene families. Genes that function abnormally when present in only one copy are called haploinsufficient. A position effect occurs when a gene's expression is altered by virtue of a change in its chromosomal position. Inversions decrease the frequency of recombinant gametes. A paracentric inversion is one whose breakpoints include the centromere.

Which Of the following is not true of inversion heterozygotes? the Inverted and non inverted homologous chromosomes have the same genes but in a different order recombination is suppressed in the Inverted region recombination can occur outside of the Inverted region they exhibit reduced viability due to duplications and deletions within the Inverted regions
