13. Through ____________________, the frequency of a gene or
allele will decline from one generation to the next if the trait
that the gene or allele codes for results in fewer offspring or
offspring of reduced quality.
14. Through ____________________, the frequency of a gene or allele
may decline dramatically within a single generation.
15. Through ____________________, the frequency of a gene or allele
will increase within a single generation as a result of migration
into the population.
16. ____________________ is the only process that can create new
genes or alleles.
17. One sex may “select” the genes or alleles that are passed to
the next generation by ____________________.
18. ____________________ usually requires a population to be
divided by a geographical barrier.
19. Genes or alleles “spread” through generations by
____________________.
20. Heritable genes, alleles, or mutations must be in
____________________ cells.
21. All genes and alleles started as a ____________________ in a
____________________ cell.
Fill in the blanks has been done below
13. Through the natural selection_, the frequency of a gene or allele will decline from one generation to the next if the trait that the gene or allele codes for results in fewer offspring or offspring of reduced quality.
14. Through Genetic drift , the frequency of a gene or allele may decline dramatically within a single generation.
15. . Through gene flow_, the frequency of a
gene or allele will increase within a single generation as a result
of migration into the population.
16. mutation is the only process that can create
new genes or alleles.
17. One sex may “select” the genes or alleles that are passed to
the next generation by sexual selection
18. speciation usually requires a population to be
divided by a geographical barrier.
19. Genes or alleles “spread” through generations by
sexual reproduction
20. Heritable genes, alleles, or mutations must be in
gametic cells.
