A mass extinction event is when over _______% of species ________   out in a relatively short period of time. More than 99% of species that have EVER lived are now ____________. Many of these extinctions occurred in a mass extinction event. 

The last mass extinction was around 65 ____________ years ago. It wiped out most _____________ species and many animal and plant species. We know this, because these species suddenly disappear from the fossil record at that time. Theories for the cause of this mass extinction include a ___________ impact or huge _____________ eruptions.

A zoo wants to assist two related endangered species with their reproduction and plans to directly implant the sperm into the female.

Which type of isolation can NOT be overcome in this way?

Two species of plants that do not cross-pollinate are an example of _____ isolation because they flower at different times of the year.

Form of reproductive isolation in which two populations develop differences in courtship rituals or other mating behaviors that prevent them from breeding. Ex. different songs or different colors

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?

A certain population of flowers only reproduces in the winter. A neighboring species only reproduces in the fall. This is an example of:

Some female peacocks prefer males with large, colorful tales while other female peacocks prefer males with no tail at all. Females are beginning to only mate with the type of males with the tail they prefer. What type of reproductive barrier is this?

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?

Based upon what your just read, what are the three possible situations that can occur if two different species mate and the chromosomes do not match?

When a zebra & horse mate, they create a "zorse". Zorses are most often sterile.
