Out of four two are heterozygous tall headed and two are homozygous short headed.
Answer:
Polar Bears
Explanation:
The species that has most likely been the most affected by human actions would be the Polar Bears. The human population is growing at a staggering rate and this causes industrialization to expand rapidly as well. This continued and increasing use of fossil fuels for all of our basic necessities is rapidly heating up our world (Global Warming) and melting the ice caps. Without this it becomes nearly impossible for Polar bears to survive as they cannot find shelter and ultimately end up starving to death due to not being able to hunt for food as well. The only way to protect them is to begin protecting our planet, switching to more environmentally friendly sources of energy, and being mindful of our choices.
