iren2701 [21]

Answer:

SEXUAL REPRODUCTION:

-creates genetically unique offspring

-organism needs time to reach adulthood to reproduce

-requires the contribution of two parents

ASEXUAL REPRODUCTION:

-creates genetically identical offspring

-organism doesn’t have to waste energy to find a mate

-requires the contribution of a single parent

Explanation:

Living organisms employ two types of reproduction to produce their offsprings. They are sexual reproduction and asexual reproduction.

Sexual reproduction is that reproduction involving the fusion of two sex cells from opposite sex individuals i.e. male and female. Sexual reproduction forms offsprings with unique genetic contents, which is as result of the meiotic process that each individual organism undergoes to produce gametes or sex cells (sperm and eggs). Since there must be a fusion of gametic cells, sexual reproduction requires the contribution of two parents (a male and a female). Also, the parents only undergo meiosis to produce gametes at certain points in their life. Hence, they have to wait to reach adulthood to do that.

On the other hand, asexual reproduction involves only the contribution of one parent as the fusion of genetic material is not needed. Hence, the offsprings form by cellular division that makes it genetically identical to the parent cell. Energy is not needed to find a mate, the organism simply reproduces on its own by dividing into daughter cells.
