) Suppose that in a species of flowering plant, we cross a plant with red flowers with a short stem with a plant with blue flowers with a long stem. The offspring all have mauve flowers and a long stem. The two characters, flower color and stem length, are found on different chromosomes. What can you conclude about the mode of inheritance of each of the characteristics of this plant species? Incomplete dominance or codominance: CºCº, simple A/a dominance b. If a progeny with long-stemmed mauve flowers from FI is crossed with a plant with short-stemmed mauve flowers, what proportion of the progeny will have the same genotype as either of the parents? Compulsory Punnett grid.

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.
