Our Chromosomes Are a Patchwork of the Chromosomes of Our Ancestors

Genetic Pedigree

Our genetic material (DNA) is packaged into physical objects known as chromosomes.  We possess two sets of chromosomes; one inherited from each of our biological parents.  These chromosomes are a mosaic of the chromosomes that our parents inherited from their parents.  As a result, our chromosomes are a complex patchwork or the chromosomes of our ancestors.  Interestingly, this chromosomal shuffling is necessary for fertility.  I am investigating the mechanism by which cells regulate this genetic phenomenon.
