Introduction Many simple forms of heritage follow the Torahs of Mendel. Dominant traits will ever be expressed when nowadays, and recessionary traits will merely be expressed when two recessionary allelomorphs are present. When traversing a pure homozygous dominant trait with a pure homozygous recessionary trait as the P coevals, it is expected that all the…

A controlled variable is a variable that stays the same throughout an experiment such as: adding a specific sum of H2O to prove tubings filled with different sums of ammonium chloride.
