Reproduction is the transfer of ____________ information from one generation to the next?

genetic

100
How many parents are needed for asexual reproduction to occur?
Only 1 parent cell is needed
100

What process creates gametes?

Meiosis

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
Name a disadvantage of asexual reproduction.
Lack of variation, organisms are more susceptible to diseases, organisms are less likely to adapt to new environments
200

In this type of asexual reproduction a new organism grow by mitosis and cell division on the the body of its parent.

budding

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

Name a disadvantage of sexual reproduction.

Organisms/Cells take a longer time to mature, Must have a mate (2 parents), Gametes (sperm/egg) can be lost, Takes more energy and time

300

In this type of asexual reproduction the cell membrane pinches inward in the middle of the cell until it splits to form two new uniform, identical offspring?

fission

300

What are the three parts of the cell cycle?

Interphase, Mitosis, Cytokinesis

300

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

fertilization

300

What are 2 advantages of internal fertilization?

Mate selection 

Protection of developing embryo 

Care of young 

300
Which type of reproduction takes more time and energy? Why?
Sexual Reproduction because it takes more time for cells to mature and organisms to be fully formed (made of many cells)
400

Runners begin to grow in this type of asexual reproduction?

Vegetative Propagation

400
Which type of asexual reproduction do most bacteria use?
Binary Fission
400

What two events in meiosis result in genetic variation in gametes?

Crossing Over (Recombination)

Independent Assortment

400

What is one advantage of external fertilization

Takes less time/energy to find a mate and reproduce

Can produce many offspring 

Can lead to increased genetic diversity

400

What is a disadvantage of external fertilization?

Lower chances of the sperm and egg meeting

Lower chances of offspring survival as the developing egg has little protection 

Less mate selection 

500

What do we call the new organism or organisms made during reproduction?

Daughter Cells or Offspring

500
Which type of asexual reproduction do plants generally use?
Vegetative Propagation
500

What is the name of two chromosomes in a pair, one from each parent, with the same genes in the same order, but different alleles.

Homologous Chromosomes

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
Which type of reproduction is more susceptible to disease (more likely to die of disease)? Why?
Asexual Reproduction because the cells are all the same and are more likely to die if a disease spreads.
