Across
- 2. Differences among individuals or populations in terms of their genetic makeup and physical traits.
- 4. The gradual change in species over time through the accumulation of genetic variations, resulting in the development of new species.
- 5. The branch of biology that studies genes, heredity, and the variation of inherited characteristics.
- 6. An early stage of development in multicellular organisms.
- 7. The genetic makeup of an organism, representing the specific combination of alleles it possesses.
- 8. An ancestral organism from which different species have evolved.
- 11. The passing of traits from parents to offspring through genetic information carried in genes.
- 12. A characteristic or trait that increases an organism's chances of survival and reproduction in a given environment.
- 14. One of the alternative forms of a gene that occupies a specific position on a chromosome.
- 15. The process by which new species arise through the accumulation of genetic differences over time, leading to reproductive isolation.
- 16. A random change in the DNA sequence of an organism, which can lead to new traits and genetic variation.
- 17. The ability of an organism to stay alive and reproduce in its environment, often influenced by various factors including adaptation and natural selection.
- 18. Similar anatomical features in different species, indicating a common evolutionary origin.
- 19. Preserved remains or traces of ancient organisms, often found in sedimentary rock layers.
Down
- 1. A diagram depicting the evolutionary relationships and common ancestry among different species.
- 3. The process by which organisms with favorable traits are more likely to survive and reproduce, leading to the gradual accumulation of advantageous traits in a population over generations.
- 6. Elements in an organism's surroundings that influence its traits and behavior.
- 9. The process by which organisms produce offspring.
- 10. Resemblances in the early stages of development among different species.
- 13. A trait or characteristic that enhances an organism's survival and reproduction in a specific environment.
