Summary Introduction
Introduction:
The chromosomes are the condensed structure of the DNA. They are X shaped and contain different DNA segments. Each chromosome has different genes and all the chromosomes in the organism makes up the genome.

Pick the statement about chromosome structure that is FALSE.
Gene duplications provide an explanation for the origin of gene families.
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 recombinate gametes.
A paracentric inversion is one whose break points include the centromere.
Genes that function abnormally when present in only one copy are called haploinsufficient.
