Across
- 4. a change in allele frequency due to chance
- 8. one of the cause of genetic variation
- 9. this leads to increased homozygousity in maize, leading to decrease in growth (1)
Down
- 1. a type of variation which the genes can have additive effect on the phenotype
- 2. an example is the change in the frequency of allele for white coat over agouti in rabbits
- 3. an example is the cheetah
- 5. to overcome (1)
- 6. used by scientiests to research the origins of species due to lack of crossing over
- 7. the capacity of an organism to survive and transmit its allele to its offspring
