Answers

1
Evolutionary pathways and natural selection may be altered by which of the following?
Eating genetically modified organisms
Using amino acid sequencing to find degrees of relatedness
Chemically killing fleas on animals
Genome sequencing of humans
2
How does production of new transgenic species have the potential to alter paths of evolution?
The creation of new genes increases biodiversity
The transfer of genes within species increases biodiversity
Transfer of genes between two species increases biodiversity
The removal of genes from a species decreases biodiversity
3
Which of the following is not a biotechnology?

4
An individual's phenotype may be affected by environmental factors. An example of this may be:

Transgenesis
Gene therapy
ELISA
CRISPR-Cas9
6
What is the best explanation for the successful development of transgenic species

Nuclear transplantation from cell to cell is easily achieved
Artificial pollination works across the plant kingdom
DNA in the biosphere is ubiquitous
7
Which of the following is true of a mutation that produces an allele that is dominant?
Would expect it to spread more quickly through a population
Could give observable phenotype only in homozygous genotype
Could give an observable phenotype in heterozygous genotype
Would be expected to cause death
