Meiosis
Natural vs Artificial Selection
100
How many parents are needed for asexual reproduction to occur?
Only 1 parent cell is needed
100
How many parents are needed for sexual reproduction to occur?
2 parents (1 male, 1 female) are needed
100
Name an advantage of asexual reproduction?
Only needs one parent, happens very quickly, offspring are clones of parents, successful characteristics are guaranteed, requires less energy and time
100

A male gamete and a female gamete join together in this process to form a zygote.

What is fertilization?

100

This type of selection is often called "survival of the fittest.

What is Natural Selection?

200
Are the daughter cells exactly the same as or different from the parent cells?
Exactly the same (identical copies)
200
Are the offspring exactly the same or different from the parents? Why?
The offspring are different because they get characteristics from the father and the mother.
200
Name an advantage of sexual reproduction.
Lots of variation can occur, Variations can help organisms to survive in new environments, Help to protect entire populations from being killed by diseases
200

This term describes the final cells produced by meiosis, meaning they contain only half the usual number of chromosomes.

What is haploid?

200

A dog breeder choosing two large, calm dogs to mate in order to create similar offspring is an example of this type of selection.

What is Artificial Selection (Selective Breeding)?

300

If the parent organism has a harmful genetic mutation, this is the chance (percentage) that the asexually produced offspring will also have it.

What is 100%?

300

When a male cell (sperm) joins with a female cell (egg/ovum) to create a zygote/new organism.

What is fertilization?

300

Which type of reproduction can occur very quickly?

Asexual Reproduction

300

This process happens in Meiosis I when matching chromosomes swap pieces of genetic material, which is a major source of genetic variation.


What is crossing over? 


300

This is what selects the favorable in Artificial Selection, making the process much faster.

What are humans?

400

This is the reason why asexual reproduction is NOT the best choice for a species living in an ecosystem that frequently changes.

What is lack of variation?

400
What is the difference between internal fertilization and external fertilization?
Internal fertilization happens inside the body, while external fertilization happens outside of the body.
400
Which type of reproduction creates organisms with a lot of variations? Why
Sexual Reproduction because the offspring get characteristics from both parents, rather than just one parent.
400

This is the final number of haploid cells produced from one parent cell at the end of Meiosis.

What is four?

400

In Natural Selection, this factor determines which traits are favorable.

What is the environment?

500

A single-celled organism like a yeast cell producing a smaller, identical daughter cell on its side is an example of this specific method.

What is budding?


500

The cell division process that creates the specialized sperm and egg cells required for this type of reproduction.

What is meiosis?

500
Which type of reproduction creates organisms that would have an easier time adjusting to a new environment? Why?
Sexual Reproduction because there are more variations amongst the organisms created.
500

The importance of meiosis for a species is that it increases this thing, allowing some individuals to survive environmental changes.

What is genetic variation (or genetic diversity)?

500

This is the primary disadvantage of traits created through Artificial Selection when those organisms are returned to the wild.

What is less likely to survive?
