The process we are referring to is called parthenogenesis, which is a form of asexual reproduction in which an unfertilized egg cell divides and develops into an embryo. Parthenogenesis can occur naturally in certain species, such as some insects, reptiles, and even some fish. However, it is relatively rare in higher organisms like mammals.

During parthenogenesis, the egg cell undergoes a series of cell divisions similar to the early stages of embryonic development. These divisions are stimulated and regulated by various molecular signals and genetic processes within the egg itself. However, it’s important to note that parthenogenesis typically results in embryos that have limited viability and often fail to fully develop into mature individuals. This is because parthenogenetic embryos lack the genetic diversity provided by fertilization, leading to higher rates of genetic abnormalities and failure to reach full term.

The exact triggers for parthenogenesis can vary depending on the species and environmental conditions. In some cases, specific signals or cues must be present for the egg cell to initiate division. These triggers can include changes in environmental conditions, such as temperature or moisture, or certain hormonal changes within the reproductive system.

It’s worth noting that while parthenogenesis can occur naturally, it can also be induced artificially in a laboratory setting. Scientists have been able to manipulate certain conditions to prompt unfertilized egg cells to divide and develop into embryos. This has been used in research to study early embryonic development and understand certain genetic and developmental processes.

In summary, parthenogenesis is a process in which an unfertilized egg cell undergoes division and develops into an embryo. While it can occur naturally in certain species, it is relatively rare in higher organisms like mammals. Parthenogenetic embryos often have limited viability, and the triggers for parthenogenesis can vary depending on the species and environmental conditions.
