Detailed explanation-1: -The classic example of mate choice is a peacock’s tail. Peahens prefer peacocks with large and colourful tails, so those peacocks get to mate more frequently and have more offspring. The male peachicks will inherit the genes for a long and colourful tail from their father and so will have a similar tail.

Detailed explanation-2: -Males are usually an iridescent shade of bright blue. This bold coloration helps them to attract mates. Females, on the other hand, have much more subdued plumage. Their feathers tend to be either brown, gray or cream in color.

Detailed explanation-3: -Males and females of certain species are often quite different from one another in ways beyond the reproductive organs. Males are often larger, for example, and display many elaborate colors and adornments, like the peacock’s tail, while females tend to be smaller and duller in decoration.

Detailed explanation-4: -The term “peacock” is commonly used to refer to birds of both sexes. Technically, only males are peacocks. Females are peahens, and together, they are called peafowl. Suitable males may gather harems of several females, each of which will lay three to five eggs.
