Answer:
A deviated septum occurs when bone and the cartilage that divides the nose septum become off-center which results in two unequal nasal septum. This makes one nasal chamber smaller and another larger.
This abnormality causes difficulty in breathing because of the congestion and blockage of the smaller nasal cavity. Due to this congestion airflow in the lungs is hindered which results in lack of oxygen and difficulty in breathing.
Apart from difficulty in breathing it can leads to nose bleeding, loud snoring during sleep, facial pain, headache, and in respiratory infections breathing become more difficult.
A deviated septum can develop due to some trauma or during surgery but some people are born with this abnormality.

Explanation:
Disparities in mate attraction that alone account for differences in reproductive success An important aspect of evolutionary biology is sexual selection. The nature and scope of sexual selection, however, have been debatable since Darwin first proposed the idea of it.
Recent debate has brought the fundamental topic of what sexual selection actually is back into focus. Incorporating female-female reproductive rivalry into sexual or natural selection is one example of this.
Sex roles are determined by differences in gametes: men generate significantly more plentiful, smaller, motile gametes whereas females produce relatively fewer, more nutritious, often non-motile gametes. There will be an excess of male gametes that will not fertilize any eggs since just one gamete of each kind is necessary to generate a child.
