What is Mendelian inheritance? a. Mendelian genes code an entire phenotype so that children will not be clones of their parents. b. Mendelian genetics are those genes that code for dominant or recessive illnesses but only if no polygenic traits cancel them out. c. Mendelian genes sit at one loci with one allele from Mom and one allele from Dad. d. Mendelian genetics is when two or more genes at two or more loci express one trait

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.
