Q.82
Gynogenesis occurs naturally in some fishes belonging to the family
- Natural Gynogenesis in Fishes:
- Gynogenesis (Pseudogamy): A form of unisexual reproduction where embryonic development is triggered by the penetration of a sperm cell, but the paternal sperm genome is excluded and does not contribute genetically to the zygote; offspring are maternal clones.
- Natural gynogenesis occurs in all-female populations of the Amazon molly, Poecilia formosa, which belongs to the family Poeciliidae. They utilize sperm from related sympatric bisexual males (Poecilia latipinna or Poecilia mexicana) solely to activate diploid egg development.
- Correct Option: Option 1 (Poecilidae).
