Across
- 3. the allele that you have does not affect your fitness because each allele is equally as good at performing its job
- 4. sum of a population's genetic material at a given time
- 6. similar physical features in organisms that share a common ancestor, but the features have different functions
- 8. a phenomenon in which there is a reduction in genomic variability when a group of organisms becomes separated from a larger population.
- 9. the change in frequency of a gene in a population due to random chance
Down
- 1. prevent mating or fertilization between different species (no fertilization)
- 2. when an organism with two different alleles of a particular gene has greater fitness than an organism with two identical copies of either allele
- 5. prevent the formation of fertile offspring after fertilization occurs
- 7. the transfer of genetic material from one population to another
- 8. the ability of an organism to reproduce and pass on genes to the next generation
