Natural selection
Across
- 2. a process that uses laboratory-based technologies to alter the DNA makeup of an organism.
- 4. The study of genes and heredity.
- 7. a method of reproduction when a single parent produces a child.
- 8. the method by which people choose the qualities they desire an organism to possess.
- 9. a number that reflects the chance or likelihood that a particular event will occur.
- 11. More environment-adapted organisms are more likely to survive and pass on the genes that contributed to their success.
- 13. a quality that sets one person or thing off from another
- 14. the possessions that a person leaves to their heirs after passing away.
- 15. the process through which organisms adapt to their surroundings to increase their chances of surviving there.
Down
- 1. selecting parents with specific traits to breed with one another and produce kids with more desirable traits
- 3. happens when the male parent's sperm fertilizes the female parent's egg, resulting in the birth of a child that is genetically distinct from both parents.
- 5. the processes used to create an exact genetic replica of another cell, tissue or organism.
- 6. the presence of differences in sequences of genes between individual organisms of a species.
- 10. Any change in the DNA sequence of a cell.
- 12. species' traits over numerous generations through the use of natural selection.
