Brazil is home to some of the most remote tribes in the world. Many of these people have not had any contact with the outside world. The Yanomami tribe is roughly 19 000 individuals, making it one of the largest tribes in the Brazilian amazon. Their land mass, which is slightly smaller than Hungary, has provided them with a wealth of resources from the forest to survive in the past. Currently, the tribe is losing land to development for mining and ranching. The Yanomami are very isolated from other tribes. As a result, individuals form tight family groups who support each other for their whole lives. The Yanomami practise polygamy, where men will have a number of wives during their lifetime. The women in the tribe are only married to one man. Based on the above information, why do the Yanomami NOT qualify as a Hardy–Weinberg population?  Select one: a. The communities migrate during the seasons and marriages are with more than one individual. b. They are not a closed population and mutations have been found. c. There is no migration and the population is not large enough. d. Natural selection is apparent and mating is not random.
