Is there any similarities between sexual reproduction and asexual reproduction?
Answers
Explanation:
While asexual reproduction only involves one organism, sexual reproduction requires both a male and a female. Some plants and unicellular organisms reproduce asexually. Most mammals and fish use sexual reproduction. Some organisms like corals and komodo dragons can reproduce either sexually or asexually. But in the long term (over several generations), lack of sexual reproduction compromises their ability to adapt to the environment because they do not benefit from the genetic variation introduced by sexual reproduction.
Comparison chart
Asexual Reproduction versus Sexual Reproduction comparison chart
Asexual Reproduction Sexual Reproduction
Number of organisms involved One parent needed Two parents are required to mate
Cell division Cells divide by Fission, budding , or regeneration Cells divide by Meiosis
Types Budding, vegetative reproduction, fragmentation, spore formation Syngamy and conjugation
Advantages Time Efficient; no need to search for mate, requires less energy Variation, Unique., organism is more protected
Disadvantages No variation - if the parent has a genetic disease, offspring does too. Requires two organisms, requires more energy
Evolution There is very little chance of variation with asexual reproduction. Mutations in DNA can still occur but not nearly as frequently as in sexual reproduction. Sexual reproduction leads to genetic variation in new generations of offspring. This is fundamental to evolution.
Involvement of sex cells No formation or fusion of gametes (sex cell) Formation and fusion of gametes (sex cell) occurs
Found in Lower organisms Higher invertebrates and all vertebrates
Unit of reproduction May be whole parent body or a bud or a fragment or a single somatic cell Gamete
Time taken Asexual reproduction is completed in a very short period of time. Sexual reproduction can take several months to complete.
Number of offspring Two or more One or more
Answer:
Similarities between sexual and asexual reproduction are,
1.In both the process new individuals are produced.
2.Both of the processes increase the number of species on Earth and in turn increases the biodiversity.
3.In both the cases, parents are involved.
