The process that allows for the transfer of traits of a peacock uses to attract a peahen is known as sexual selection.
Natural selection is referred to as sexual selection when a member of a population of a species has an advantage over other members of the same sex in attracting partners for copulation. These members will have a higher likelihood of procreating and increasing in number.
The male peacock is an example of sexual selection because of his colorful feathers, which he flashes to attract a peahen. Bright feathers on the male peacock are a common phenotypic advantage to attract peahens, favoring sexual selection. This enables the transmission of this trait from parents to offspring, enabling them to grow in number and adapt to a mate-seeking environment with other members.
