The answer is polygenic inheritance.
Many physical characters (traits) depend on many different factors, each of which is determined by different genes. This is called polygenic inheritance.
For example, the color of the skin in humans. The color of the skin results from the interactions of several factors determined by different pairs of genes:-Certain genes could affect the metabolism of skin melanocytes.-Other genes can determine the distribution of melanin in the thickness of the skin.-Some genes could determine the relative amounts of each of the two possible types of melanin.-Others may affect the production of certain hormones involved in the activity of melanocytes.
Answer:
its being called a miracle because mules aren't supposed to give birth haha, they're sterile, they can't make sperm or eggs because their chromosomes don't match up well, and coz of chromosomes number.
Explanation:
for example they have 31 and horses have 32 pairs of chromosomes so they cant match with anythin
Answer;
-Kinetic energy
Explanation;
The energy associated with motion or movement is called kinetic energy.
-Kinetic and potential energies are found in all objects. If an object is moving, it is said to have kinetic energy (KE). Potential energy is stored energy and the energy of position; gravitational energy.
-An object that has motion - whether it is vertical or horizontal motion - has kinetic energy. Kinetic energy is calculated by the formula 1/2mv², where m is the mass of the object and v is the velocity of the object.
-Therefore, kinetic energy depends upon two variables: the mass (m) of the object and the speed (v) of the object.
They are reactants because they are present before the reaction.
