Asexual Reproduction

Advantages :

1. Asex­u­al­ly repro­duc­ing ani­mals do not require to spend unnec­es­sary time and ener­gy in locat­ing a mate, cop­u­lat­ing and nur­tur­ing their offspring
2. Asex­u­al repro­duc­tion is very ben­e­fi­cial for ses­sile organ­isms or organ­isms with kow pop­u­la­tion densities.
3. One advan­tage of asex­u­al repro­duc­tion is that a con­stant com­bi­na­tion of genes match­es a sta­ble , unchang­ing envi­ron­ment in which the ani­mal lives.

Disadvantages:

1. Asex­u­al repro­duc­ing species tend to evolve very slow­ly, because all off­spring pro­duced by of any one of the indi­vid­ual are alike , pro­vid­ing less genet­ic diver­si­ty foe evo­lu­tion­ary selection.
2. Since genet­ic diver­si­ty does­n’t occur so even a sin­gle envi­ron­men­tal event May destroy an entire species.

Sexual Reproduction

Advantages:

1. Increased diver­si­ty because of new com­bi­na­tions of genes due to fer­til­iza­tion enables sex­u­al­ly repro­duc­ing ani­mal pop­u­la­tions to adapt to new dis­ease and chang­ing envi­ron­ment conditions.
2. If sex­u­al­ly repro­duc­ing pop­u­la­tion is threat­ens with dis­ease or dras­ti­cal­ly chang­ing envi­ron­ment at least some mem­bers of the pop­u­la­tion will be able to resist, adapt and sur­vive the dis­ease or the chang­ing envi­ron­ment because of their genet­i­cal­ly diverse gene pool.

Disadvantages:

1. The essen­tial require­ment to locate a mate for repro­duc­tion is dif­fi­cult to accom­plish in Ses­sile organ­isms or organ­isms with low pop­u­la­tion densities.
2. Time and ener­gy is wast­ed in locat­ing a mate , attract­ing it, cop­u­lat­ing and nour­ish­ing the offsprings.
3. Expo­sure to pre­da­tion dur­ing the mat­ing May occur.
4. Expo­sure due to dis­ease from the mate May occur.
