The law of independent assortment states that traits are passed from parents to offspring independently of one another; therefore the traits are independently assorted.
Explanation:
The law of independent assortment is also known as Mendel's 2nd law of heredity.
It states that during gamete formation, the way one pair of alleles for a given trait distributes itself in the gametes does not affect the way other pairs of alleles (for other traits) distribute themselves.
Mitochondria (The powerhouse of the cell). Muscle cells need more energy since they work to support the body, lift things, etc. Epithelial cells don't need as much energy since they only line organs/blood vessels and don't need to use as much energy.
