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
