Answer:
The Y chromosome do not go through crossover
Explanation:
Typically, genes from the mother and father are shuffled -- or, "cross over" -- to produce a genetic combination unique to each offspring. But the Y chromosome does not undergo crossing over, and, as a result, its genes tend to degenerate, while repetitive DNA sequences accumulate. Each chromosome is made up of DNA.

Answer:Mostly the stars, planets and heat
Explanation:The stars are smaller versions of the sun they do rotate around the sun like the planets, they are very hot they give the sun more heat to produce.
