Two genes are on separate chromosomes (i.e., unlinked). One homologous pair of chromosomes carries the 'A' and 'a' alleles, while another homologous pair of chromosomes carries the 'B' and 'b' alleles. Based on what you know about Independent Assortment and probability, what percent of the time will the following occur: 1. 'A' goes with 'B' and 'a' goes with 'b'? 2. 'A' goes with 'b' and 'B' goes with 'a'? Therefore, can we compute a distance of 60 map units for two genes by a two point cross? Yes or No. Why?

Mitochondrial Mutations

A mitochondrion is a cellular organelle that serves as the site for cellular respiration and energy production (ATP or Adenosine Triphosphate). It is a double-membrane-bound organelle and is only present in eukaryotic cells.
