Fruit flies are beginning to live & mate on different types of fruit on the floor of the Amazon. Bigger fruit flies prefer rotting mangos, while smaller fruit flies prefer rotting bananas. What type of reproductive barrier is this?

• habitat isolation

• temporal isolation 

• gametic isolation

• mechanical isolation 

A flash flood carried a raft of Amazon ants away from their original population. There is enough distance between the two groups, that they will never meet in nature again. What type of reproductive barrier is this?

• behavioral isolation

• temporal isolation 

• gametic isolation

• geographic isolation 

The pollen (sperm) of a flowering plant cannot fertilize the egg cell of a nearby flowering plant of its kind. What type of reproductive barrier is this?

• behavioral isolation

• temporal isolation 

• gametic isolation

• geographic isolation 

When reproductive barriers separate a population of a species in nature, the species no longer share a... 

• taxa

• gene pool 

• phylogenetic tree

• species 

The genitalia of the male damselfly varies in shape. Certain males can only hold onto & mate with females whose genitalia fit.  What type of reproductive barrier is this?

• behavioral isolation

• temporal isolation 

• gametic isolation

• mechanical isolation 

When a zebra & horse mate, they create a zorse. Zorses are most often sterile. What type of reproductive barrier is this?

• behavioral isolation

• hybrid sterility 

• gametic isolation

• mechanical isolation
