What's the difference between natural selection and selective breeding?

In natural selection the "unfit" animals die off, in selective breeding, animals only...um...breed...with animals who meets their requirements.

The difference between natural selection and selective breeding is natural selection happens naturally and selective breeding only occurs when humans intervene 

hope this helps

Maybe haha

The main role of dna in the  cell is the long-term storage of information. it is often compared to a blueprint, since it contains the instructions to construct other components of the  cell, such as  proteins  and rna molecules.the main function of rna is to carry information of amino acid sequence from the genes to where  proteins  are assembled on  ribosomes  in the  cytoplasm. mark brainliest, my work is good.
