5 Questions
What is asexual reproduction?
Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes. The offspring inherit the full set of genes of their single parent and are genetically and physically similar to the parent.
Which organisms primarily reproduce asexually?
Single-celled organisms such as archaea and bacteria primarily reproduce asexually, but many eukaryotic organisms including plants, animals, and fungi can also reproduce asexually.
What is the most common form of asexual reproduction in vertebrates?
The most common form of asexual reproduction in vertebrates is parthenogenesis, which is typically used as an alternative to sexual reproduction in times when reproductive opportunities are limited.
What is an example of a vertebrate that can reproduce asexually?
Komodo dragons and some monitor lizards can reproduce asexually.
How do prokaryotes reproduce?
All prokaryotes reproduce without the formation and fusion of gametes, and there are mechanisms for lateral gene transfer.
Study Notes
Asexual Reproduction
- Asexual reproduction is a type of reproduction that does not involve the fusion of gametes (sex cells) from two parents.
- It involves the production of offspring genetically identical to the parent organism.
Organisms that Reproduce Asexually
- Organisms that primarily reproduce asexually include bacteria, archaea, and some protozoa.
Asexual Reproduction in Vertebrates
- The most common form of asexual reproduction in vertebrates is parthenogenesis.
- Parthenogenesis is a process where an offspring develops from an unfertilized egg cell.
Examples of Asexual Reproduction
- One example of a vertebrate that can reproduce asexually is the boa constrictor, which can reproduce parthenogenically.
Prokaryote Reproduction
- Prokaryotes, such as bacteria, reproduce asexually by a process called binary fission.
- Binary fission involves the division of a prokaryotic cell into two identical daughter cells.
