Question

Male peacocks are very brightly coloured to help attract mates while the females are dull coloured. What concept decribes such a phenomenon?

Answer 1

Answer:

Explanation:

• According to Drawin theory it is called sexual selection which states that during breeding season females tends to select males with brighter colour and are  mostly attracted by it hence though evolution male peacocks have developed more brightly coloured feathers.
• But it may not be true in every case as female peacock has incubation periods so to be safe from potential predators they tend to be dull coloured and are merely visible to such predators which are extreme threat.
• some theories suggest that bright colouration indicate dominance over a particular area and threat to others who tend to take over the area occupied.The red shoulder patch on red-winged blackbirds provides an excellent example. The patch is coverable and is shown to males and females of the same species but never to predators. Males who had their patch experimentally covered tended to lose their territories more often than did uncovered birds.

I HOPE THIS IS HELPFUL
