16-3 Speciation

When two populations are capable of interbreeding but have differences in courtship rituals or other mating strategies.

• behavioral isolation

• geographic isolation

• reproductive isolation

• temporal isolation

When two populations are separated by physical barriers such as rivers, mountains, or bodies of water.

When two or more populations reproduce at different times.

• behavioral isolation

• geographic isolation

• reproductive isolation

• temporal isolation

When parts of a population cannot reproduce with others. Over time, members of the isolated population will become so different that they no longer mate and produce fertile offspring with the original population.

• behavioral isolation

• geographic isolation

• reproductive isolation

• temporal isolation

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

• behavioral isolation

• reproductive isolation

• temporal isolation

• geographical isolation

The flowers of pink tulips open in the morning, while the flowers of lavender tulips open in the early afternoon. The bees that pollinate these tulips cannot carry pollen back & forth between the two types of tulips because of their flowers being closed at different times of day. What type of reproductive barrier is this?

• behavioral isolation

• reproductive isolation

• temporal isolation

• geographic isolation

The term for the formation of new and distinct species over the course of evolution is...

• speciation
• biological species concept
• reproductive barrier
• natural selection

What is a species? 

• A group of organisms that can mate with each other and produce fertile offspring. 
• A group of organisms that can mate and produce offspring even if those offspring are infertile.
• A group of organisms that genetically are very different from each other. 
• Indivual organisms that live in the same environment.

A horse and a donkey can successfully mate to produce offspring known as a mule. Mules are sterile, which means they cannot reproduce. Would mules be classified as a species?

• Yes, mules have enough of their own traits

• Yes, mules have a different number of chromosomes

• No, mules are too similar to the parent species

• No, mules cannot reproduce their own kind
