Across
- 3. trait controlled by two or more genes
- 7. principle that allele frequenciesin a population will remain constant unless one or more factors cause the frequencies to change
- 8. trait controlled by a single gene
- 9. form of natural selection by which the center of the curve remains in its current position; occurs when individuals near the center of a distribution curve have higher fitness than individuals at either end
Down
- 1. form of natural selection in which the entire curve moves;occurs when individuals at the upper and lower ends of a distribution curve have highr fitness then individuals near the middle
- 2. situation in which allele frequencies remain constant
- 4. number of times an allele occurs in a gene pool compared with the number of times other alleles occur
- 5. form of natural selection in which the entire curve moves; occurs when individals at one end of a distribution curve have higher fitness then individuals in the middle or at the other end of the curve
- 6. change in allele frequencies as a result of the migration of a small subgroup of a population
- 10. combined genetic info of all the members of a particular population
