How does natural selection work with regards to genes and what is passed to the next generation?
a
Those with the least favorable combination of genes survive and pass their DNA to the next generation.
b
Those with the most favorable combination of genes die off not allowing their DNA to be passed on to the next generation.
c
Natural selection allows genes to mutate, therefore changing the species.
d
Those with the most favorable combination of genes survive and pass their DNA to the next generation.
