Final answer:
Parthenogenesis is the mode of reproduction where females produce offspring from unfertilized eggs, resulting in genetically similar or identical progeny, seen in some insects, fish, and reptiles.
Step-by-step explanation:
The mode of reproduction in which females produce genetically identical offspring from unfertilized eggs is known as parthenogenesis. This form of asexual reproduction can result in either haploid or diploid offspring, depending on the species and the process. For example, in haplodiploidy, which occurs in some insects like bees and wasps, unfertilized eggs develop into haploid males, whereas fertilized eggs develop into diploid females. In certain vertebrates, such as some fish, reptiles, and turkeys, parthenogenesis can also occur, often resulting in progeny that have only maternal chromosomes and are therefore genetically similar to their mother.
