Poor genes can lead to extinction by causing lives to become shorter due to higher incidences of death by disease or weakness. These poor genes combine with other poor genes to create people or animals that are unable to live long and healthy lives.
yes
There are many ways.
Extinction.
The evolution of mammals
The organism that is reproducing is not doing it so that it may live, but so that its genes may be passed on. Without reproduction a population would dwindle rapidly and lead to the extinction of an entire species.
Yes poor reproductive succes does lead to extinction most of the time. for example the whooping crane reproduces very slowly. The first fledging to emerge from its egg kills its brother or sister. Less animals, slow reproduction. If there were ever accidents or if the animal died, and they never had babies, the more and more often that this happens the more likely that animal is to eventually become extinct.

Deforestation of rainforests will likely lead to extensive extinction of species.
extinction. Extinction occurs when a species cannot adapt to changing environmental conditions or when human activities lead to their decline and eventual disappearance.
cheetah's aren't extinct...... but like poachers and stuff could eventually lead to their extinction.
Deforestation of rainforests will likely lead to extensive extinction of species.
Homeotic genes, also known as Hox genes, are responsible for controlling the identity and positioning of body parts during embryonic development. Mutations in these genes can lead to dramatic changes in body structure, such as transformations in the identity of entire body parts.
