Biology

3. factor where changes in a habitat affect the organism's survival
5. different looking species can have similar internal systems
6. force that causes a specific phenotype to be more advantageous
11. factor where differences between organisms of the same species
16. factor where there is a difference in genes passed on to new generations
17. the letters that represent a trait
18. factor species produces more offspring than can survive
20. varian in dna
21. factor where members of a species fight for same supplies
22. still present but no longer used (goosebumps)
24. one dominant and one recessive allele
25. the ability for organisms with more advantages to be able to reproduce more

1. advantage that organism has that is developed overtime
2. tool to determine a common ancestor
4. have the same functions but arent from a common ancestor
7. the theory that organisms with more advantageous traits are more likely to survive
8. the visible trait that comes from the genotype
9. the genetic formation that contains genetic instructions for organisms
10. shows how the same species evolved over time and developed better traits
12. sections of dna that code for specific traits
13. different forms of the same gene
14. a characteristic of an organism
15. have different functions but come from a common ancestor
19. a way to visualize possible genotypes of the offspring
23. a change in a species over a long period of time
