If both parents have the recessive traits, the offspring will
also have the recessive trait
will still have the dominant trait
If one parent has the dominant trait, but the other carries the recessive trait
the offspring will most likely have the dominant trait still.
the offspring are guaranteed to have the recessive trait.

budding
fission
fragmentation
sporulation
What are some advantages of asexual reproduction are: (select all that apply - there are 3)
it only requires one organism

offspring are already well-adapted for the environment
there is a lot of genetic variety
Some advantages of sexual reproduction include: (select all that apply - there are 3)
genetic variation
improves chances of adapting to the environment
helps species survive catastrophes
it doesn't take as much energy as asexual reproduction
