Across
  1. 2. Selection within sexes (involves competition)
  2. 4. A form of natural selection that favours individuals at both extremes of the phenotypic range; can lead to speciation
  3. 7. ______________ depressing is reduction in biological fitness—survival, fertility, and growth—of offspring resulting from mating between closely related individuals
  4. 9. _________________-dependent selection is defined as when the fitness of a phenotype depends on how common it is
  5. 11. In this type of mating, individuals prefer to mate with others that share similar traits
  6. 13. This form of selection occurs when natural selection maintains stable frequencies of two or more phenotypic forms in a population
  7. 15. All of the alleles present in a population (2 words)
  8. 16. This form of selection involves the careful breeding of animals or plants with desired traits
  9. 17. In some circumstances, these genotypes may have a higher fitness than do individuals with two of the same alleles
Down
  1. 1. A form of natural selection that favours intermediate variants and acts against extreme phenotypes
  2. 3. The type of selection that leads to individuals with certain characteristics being more likely than others to obtain mates
  3. 5. A form of natural selection that favours individuals at one extreme end of the phenotypic range
  4. 6. Selection does not mean this, because a number of different factors influence adaptation by evolution
  5. 8. _______________ depression happens when crosses between two genetically distant groups or populations result in a reduction of fitness
  6. 10. A localized group of individuals capable of interbreeding and producing fertile offspring
  7. 12. Hardy Weinberg Equilibrium can be used to determine if a population is doing this
  8. 14. Selection between sexes (involves mate selection)
