What is the phenomenon where aphids are pregnant with pregnant aphids?

• A. Telescoping generations
• B. Consecutive clonal generations
• C. Polyphasic reproduction
• D. Synchronous life cycles

Answer: (A)

Telescoping generations describes the situation in aphids where a female produces daughters who are already pregnant with their own embryos. This happens because aphids commonly reproduce asexually (parthenogenesis) and give birth to live young, so the offspring can themselves be carrying developing offspring. As a result, you can have a generation inside the womb of the previous one, leading to rapid, layered reproduction. This is why the phenomenon is described with a term that captures generations sliding into one another. The other concepts don’t capture this specific nesting of generations: consecutive clonal generations would refer to a line of clones without highlighting the pregnant condition, polyphasic reproduction involves alternating sexual and asexual phases, and synchronous life cycles describe timing rather than the pregnancy of the offspring.
