their offspring will inherit their favorable traits
The adaptations and the variations among the organism change each generation of the organism
From the process of replication of a cell
Yes. Sexual reproduction is more advantageous than asexual reproduction in a challenging environment since sexual reproduction introduces more variation in the offspring. In asexual reproduction, the variation in offspring is caused by mutations and they are rare and a large number of offspring will have to be produced to ensure enough offspring with beneficial mutations are born, and this is not always possible when resources are scarce. In sexual reproduction, variation is introduced by recombination in addition to mutation, and recombination (random crossover of chromosomes) happens in every time the organism reproduces to introduce variation that may not be present in the parents. The greater amount of variation increases the chance of having offspring that are adapted to the challenging environment.
Sexual reproduction results in a greater variety of inherited traits because it combines genes from two different individuals. Asexual reproduction is simply a copy of an organism's genetic material so that it is a 100% match. Sexual reproduction combines different gene pools as well to create more diversity.
Sexual reproduction causes most variation in organisms. This is because genes get mixed up in the process whereas in asexual reproduction the offspring is genetically identical to the parent.

Sexual reproduction means there is much greater scope for genetic variation of offspring. Variation is good for any species as it is this variation that allows for adaption e.g. the variation might provide some individuals with resistance to a new disease that affects the species, hence those individuals survive and thrive.

Sexual reproduction produces individuals with genes from two parents, which increases the combinations of alleles possible in a population. This increase in combinations of alleles can be useful when changes in the environment occur requiring new adaptations. Populations with large stores of variation can, in general, adapt better to those changes because they already have the necessary variation in place.
Asexual reproduction decreases genetic variation which is the raw material on which natural selection operates. This is because asexual reproduction produces identical offspring to the parent.
There is less variation with asexual reproduction.
Environmental changes almost demand variation in organisms so that the best fitted to the changing environment survive and reproduce in a greater number. Asexual reproduction produces clones with little to no genetic variation. Good enough for a static environment, but in a challenging environment with no variation that could be more beneficial than cloning the asexual species could find itself selected against.
Sexual reproduction makes use of meiosis, which has the unique property of introducing variation in the offspring by means of recombination. Asexual reproduction, which depends on mitosis, can only rely on mutations as a source of variation. Mutations, however, are rarer and more unpredictable than recombination and are not suited to rapidly create a new variation of the old strain that is specifically more adapted to the current environment.

neutral variation
No. Asexual reproduction provides no diversity, as it creates an exact copy of the organism. Sexual reproduction, on the other hand, provides diversity by using and combining different genes each time to create an entirely new version of the organism.
