An equational division of mitosis is occuring for a diploid organism that has three heterologous chromosomes. One acrocentric, one metacentric and one telocentric. The organism is tetrahybrid and heterozygous for dominant and recessive alleles at four different loci. The parental genotypes were AAbbCCDD and aaBBccdd.  Locus A and B are on the telocentric chromosome. Locus C is on a metacentric chromosome. Locus D is on the acrocentric chromosome. Part A: How many distinct gametes are possible if this cell goes through meiosis but does not have any crossing over (chiasma) during meiosis I. Explain your reasoning Part B: Draw one possible representation of the chromosomes in a cell after the equational division of meiosis. Include all centromeres, chromatids and alleles.

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.
