Parent cross RRAA x rraa

Gamete: RA x ra

F1 gen. RrAa

Selfing of F1. RrAa x RrAa

F2 offspring

Rr x Rr Aa x Aa

A farmer raising cattle for beef production has divided his range into four quadrants of equal size which quadrant of range land
Kaylis [27]

Answer:

The quadrant with more probabilities of overgrazing would be the one in which the drinkers and the rest zone is.

Explanation:

When a farmer has cattle for beef, most of them divide the land in quarters and limit each of them, this is to keep the cattle in only one quarter to make sure they eat all the forages in there and then they pass to the next quarter, this gives the other quarters (the forage) time to grow properly.

If the farmer uses all the four quarters, the  natural behavior of the cattle would make the quarter that has the drinkers and the rest zone to be more likely to have an overgrazing.

This is because cows look for their aliments near them and near their comfort zone, they only move when the forage of that area is over.

In general, how does biodiversity vary across the biosphere?
Tamiku [17]
Life needs energy, water, heat and nutrients. Reduce the availability of one or more of those things and biodiversity generally decreases.

Tropical forests tend to be more diverse than polar ice caps. However, arctic seas tend to be more biologically interesting than the middle of the Sahara. I bet this is what your homework is looking for but it's important to remember there are counterexamples.
