Correct answer: Law of dominance
According to Mendel's law of dominance when a cross is done among the parents that are true for contrasting traits, then in such a situation only one of the trait will be shown in the next generation, and the other will be hidden. It will appear in the trait that is dominant.
The alleles that are expressed in the population are called as dominant while the trait that does not express is called a recessive trait.
Natural selection is the differential survival and
reproduction of individuals due to differences in phenotype. It provides a
viable explanation for adaptation and speciation as it explains the change in
heritable traits characteristic of a population over time. Changes that allow an organism to better adapt
to its environment will help it survive and have more offspring. Natural
selection can change a species in small ways, causing a population to change
color or size over the course of several generations. Given enough time and
enough accumulated changes, natural selection can create entirely new species. It
can turn dinosaurs into birds, amphibious mammals into whales and the ancestors
of apes into humans.

Answer:
Animals need resources to survive.
Explanation:
With a lack of enough resources for various animals, it generates competition for resources and eventually animals will start to starve and die off.
