The phrase to fit into the blank is "sexual reproduction"!
In sexual reproduction each of the parents produces a gamete and contributes to half of the offspring's genes. This means that the offspring is a unique composition of the two parents.
In contrast, in a asexual reproduction, the offspring would likely have the same genetic code as the parent.

Answer:
Do you mean planets?
if so,The heavy rocky particles within the inner part of the disk formed planetesimals and eventually, inner planets. In our solar system, the four innermost planets Mercury, Venus, Earth and Mars are known as inner planets. They lie inside the asteroid belt. They have volcanoes and valleys and are very hot compared to outer planets.Inner planets are much smaller than the outer planets, and are rocky with an iron core.
Hope that helps!
