Sexual vs. Asexual Reproduction What’s the difference???
Asexual Reproduction • Formation of new, individual organism from the cell(s) of a single parent
Occurs in organisms like plants (taking cuttings, runners re-rooting)
Certain animals like sponges, insects, reptiles and fish can do asexual reproduction
PROS Don’t need to find mate Can stay in one place Less energy expended Can produce a bigger population more quickly CONS No genetic variation Population of clones Advantages and Disadvantages of Asexual Reproduction
Sexual Reproduction • Two individuals produce offspring that have genetic characteristics from both parents • Requires fertilization by specialized sex cells made by meiosis
PROS Genetic variation can lead to new traits, better survival and aid evolution CONS Requires more energy to find mate and process usually takes longer Slower population growth Advantages and Disadvantages of Sexual Reproduction
Asexual Reproduction Sexual Reproduction -Only one parent -Offspring are genetic clones of parents -No genetic variation! -In some organisms, it is as simple as MITOSIS -Requires two different parents -Specialized sex cells, made by MEIOSIS -Lots of genetic variation, good for evolution Method of reproduction
