Sexual reproduction involves the joining of two specialized cells called gametes, one from each of two parents. The offspring that result are genetically unique; they have a mixture of genes from both parents.
-requires two parents and only about half of the offspring can reproduce.
-genetic variation allows a species to survive or possibly thrive in changing or different environments.
Asexual reproduction is the creation of offspring from a single parent and does not involve the joining of gametes. The offspring that result, for the most part, genetically identical to each other and to the single parent.
- more efficient in relatively unchanging environments than sexual reproduction.
-requires only one parent organism, and all of its offspring can reproduce.
-In a changing environment, their genetic uniformity can lead to problems if the environment drastically changes.
