That all cells arise from pre-existing cells.
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.

<h2>
Reproductive Method </h2>
Explanation:
<em>The rank in order from the most specific which is following .</em>
<em>(1) Reproductive isolating mechanism</em>
<em>(2) Sperm-egg incompatibility in sea urchins</em>
<em>(3) Gametic isolation </em>
<em>(4)Prezygotic isolating mechanism</em>
<em>(1) Reproductive isolating mechanism-</em> The components of regenerative confinement are an assortment of transformative instruments, practices and <em>physiological procedures basic for speciation.</em> They keep individuals from various species from delivering posterity, or guarantee that any posterity are sterile.
(<em>2) Sperm-egg contradiction in ocean urchins-</em> Bindin is a gamete acknowledgment protein known to control species-explicit <em>sperm-egg grip</em> and layer combination in ocean urchins.
<em>
(3)Gametic isolation - Prezygotic hindrances </em>keep preparation from occurring. Gametic disengagement is a sort of prezygotic hindrance where the<em> gametes (egg and sperm) </em>come into contact, yet no preparation happens. Gametes might be not able to remember each other in various species
<em>
(4) Prezygotic isolating mechanism- </em>while postzygotic segregation forestalls the arrangement of rich posterity. Prezygotic systems incorporate environment segregation, mating seasons, "mechanical" disconnection, gamete detachment and conduct seclusion.
