Card #1
Front (Question/Term)
A remote island is colonized by a single female insect capable of parthenogenesis (asexual reproduction). Five years later, the island is crowded with her identical clones. However, a new parasite arrives that targets their specific immune protein. Why is this population at a higher risk of total extinction than a sexually reproducing one?
Back (Answer/Definition) ANSWER
The lack of "Crossing Over" during meiosis means they lack the genetic recombination needed to produce an offspring with a mutant, resistant protein.
Card #2
Front (Question/Term)
If you were to chemically inhibit "Crossing Over" during meiosis in a flowering plant, what would be the most likely long-term impact on that plant’s lineage?
Back (Answer/Definition) ANSWER
The offspring would become genetically identical to the parents, reducing the "diverse genetic toolkit" available for environmental adaptation.
Card #3
Front (Question/Term)
Why is reproduction described in your material as a "universal feature of all known life" rather than just a biological option?
Back (Answer/Definition) ANSWER
Because it is the only process that ensures the continuity of a species and prevents its inevitable extinction over time.
Card #4
Front (Question/Term)
A gardener grows tomatoes from "cuttings" (clones), while a neighbor grows them from "seeds" (sexual reproduction). During a severe heatwave, the neighbor's garden survives while the gardener's dies. What biological principle explains this?
Back (Answer/Definition) ANSWER
Sexual reproduction reshuffles genetic material, meaning some of the neighbor's plants likely inherited a natural tolerance to heat.
Card #5
Front (Question/Term)
In an environment that is rapidly changing and highly stressful, why is sexual reproduction considered an evolutionary "investment"?
Back (Answer/Definition) ANSWER
It creates variations via genetic recombination, increasing the probability that some offspring will survive new threats.
