Term | Definition |
sexual reproduction | Two parents sharing genetic information so the offspring has a combination of traits from each parent |
asexual reproduction | One parent producing offspring with the same DNA |
uniform | having the same exact traits |
diverse | having different traits |
Fission (Binary) | Type of asexual reproduction where a single celled organism divides and splits into 2 separate organisms. You can not differentiate the original parent from the offspring |
Budding | Type of asexual reproduction where the parent produces a smaller clone of itself (mini me) and then pops it off. The original parent cell still remains. |
Fragmentation | An organism will break off a piece of itself and both parts regrow to become fully functioning organisms |
Regeneration | When a lost part of an organism can regrow. Not truly asexual reproduction because a new organism is not formed. |
Give an example of an organism undergoing fission. | Ameoba |
Give an example of an organism undergoing budding. | Hydra |
Give an example of an organism undergoing fragmentation. | Planarian |
3 types of asexual reproduction | fission, budding, fragmentation |
Advantages of asexual reproduction | Fast, many offspring in a short amount of time |
Disadvantages of asexual reproduction | all organisms have the same DNA and traits, so the species does not tolerate changes in the environment well |
Sperm | male sex cell in mammals- only has 1/2 the chromosomes |
Egg | female sex cell in mammals- only has 1/2 the chromosomes |
Zygote | cell formed when the male and female sex cell combine. Has the full number of chromosomes |
Advantages of sexual reproduction | The organisms of the population have different traits. This gives the population as a whole a better chance to tolerate changes in the environment |
Disadvantages of sexual reproduction | Slow. Not very many new offspring over a period of time |
