In frogs, different mating seasons are a barrier to reproduction.
Charles Darwin's theory of pangenesis, in which every part of the body contributes to an egg or sperm, implied blending inheritance. Darwin's theory of natural selection was founded on the premise that blending inheritance would average out any novel beneficial trait before selection could act.
<h3>What is blending inheritance?</h3>
Blending inheritance is an outmoded biological theory from the nineteenth century. According to the theory, children inherit any characteristic as the average of their parents' values for that characteristic.
As an example, a cross between a red flower variety and a white variety of the same species would result in pink-flowered offspring.

Thus, this can be the importance of blending inheritance.

Answer;
-Down the concentration gradients; evenly distributed
Diffusing molecules move down the concentration gradients until they are evenly distributed.
Explanation;
Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration.
-Whenever a substance exists in greater concentration on one side of a semipermeable membrane, such as cell membranes, any substance that can move down its concentration gradient across the membrane will do so. If the substances can move across the cell membrane without the cell expending energy, the movement of molecules is called passive transport.
-The mechanism of molecules moving across a cell membrane from the side where they are more concentrated to the side where they are less concentrated is a form of passive transport called simple diffusion.
