Ornithorhynchus (platypus) is an oviparous mammal, meaning it lays eggs instead of giving birth to live young.
Ref: NCERT Class 11 Biology Chapter 4: Animal Kingdom Vertebrata - Aves and Mammalia
Ovoviviparous animals, such as some sharks, retain eggs inside the female's body until hatching.

Echinoderms have separate sexes, and fertilization occurs externally in water.
Ref: NCERT Class 11 Biology Chapter 4: Animal Kingdom Phylum Arthropoda
Echinoderms are primarily dioecious and reproduce sexually with external fertilization. Although some show asexual reproduction, it is not the common mode.
Ref: NCERT Class 11 Biology Chapter 4: Animal Kingdom Phylum Aschelminthes and Annelida
In oogamous reproduction, a large, non-motile egg fuses with a small, motile sperm, as seen in Volvox and Fucus.

Viruses are inert outside their specific host cells. After infecting a living cell, they take over the host-cell machinery to produce new viral particles; therefore, they are obligate parasites.

Bacteria reproduce mainly by fission. Under unfavourable conditions, some bacteria may also produce spores, and a primitive type of DNA transfer may occur between bacterial cells.
Ref: NCERT Class 11 Biology Chapter 2: Biological Classification Bacteria - Structure and Economic Importance
Bacteria reproduce mainly by fission. Some produce spores under unfavourable conditions, while a primitive type of sexual reproduction may occur through the transfer of DNA from one bacterial cell to another.

Monogamy reflects key principle in quiz on mating behavior+pyqs, where evolutionary mechanisms shape genetic variation and adaptation. In this context, Monogamy aligns with experimental and theoretical evidence from population genetics, behavioral ecology and molecular phylogeny. Textbooks like Campbell Biology, Futuyma Evolution and Hartl Principles illustrate supporting data. Understanding why Monogamy fits helps integrate natural selection, environment.
