4. A population of insects is found on an island. When discovered, the population is 60% green and 40% brown. A hurricane strikes the island, randomly killing a large portion of the insect
population. When scientists return after the hurricane, the population is found to be 20% green
and 80% brown. This sudden change in the allele frequencies due to the hurricane is best
described as -
A recombination
B mutation
C genetic drift
D gene flow

Plz genetic engineering can be applied to many fields including medicine and agriculture. which of the following is a medical application of genetic engineering? a. giving crop plants recombinant dna so that they would be resistant to herbicides. b. examining a persons pedigree to determine whether they can carry a gene for a genetic disease. c. analyzing a persons dna to see how closely they are related to another person. d. certain genes into bacteria so that they will produce a needed medicine.

Give an example of a trait that is controlled by more than one gene.
