Parthinogenesis | Method of asexual reproduction#Parthinohenesis
Parthenogenesis (Greek: παρθένος, parthenos, "virgin" + γένεσις, genesis, "creation") is a type of asexual reproduction where an offspring develops from an unfertilized egg cell. This means that the offspring is produced without the involvement of a male gamete (sperm) and without fertilization.
In parthenogenesis, the egg cell develops into an offspring that is genetically identical to the parent, since there is no mixing of genetic material from two parents. This process is commonly seen in some species of:
1. Insects (e.g., aphids, bees, wasps)
2. Reptiles (e.g., some species of snakes, lizards)
3. Fish (e.g., some species of sharks, rays)
4. Plants (e.g., some species of flowers, like roses)
Parthenogenesis is an important reproductive strategy in some species, allowing them to reproduce and adapt to their environment without the need for a male partner.

Here's a note on the types of haploid and diploid parthenogenesis:
Haploid Parthenogenesis
Offspring develop from an unfertilized egg cell (n) without meiosis
Resulting offspring are haploid (have only one set of chromosomes)
Examples:
Bacteria
Some fungi
Some protists
Diploid Parthenogenesi
Offspring develop from an unfertilized egg cell (2n) with meiosis
Resulting offspring are diploid (have two sets of chromosomes)
Examples:
Some insects (e.g., aphids, bees)
Some reptiles (e.g., some species of snakes, lizards)
Some fish (e.g., some species of sharks, rays)
