Questions 7

Answers

1
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
Would be expected to cause death
Could give an observable phenotype in heterozygous genotype
Could give observable phenotype only in homozygous genotype
2
An individual's phenotype may be affected by environmental factors. An example of this may be:
Exposure to nuclear radiation increasing fetal abnormalities
studying biology improving an HSC student's intelligence
stressful situations causing alternate gene expression
High calcium diets making bones stronger
3
What is the best explanation for the successful development of transgenic species
Nuclear transplantation from cell to cell is easily achieved
DNA in the biosphere is ubiquitous
Genes from animals within one species are easily combined
Artificial pollination works across the plant kingdom
4
How does production of new transgenic species have the potential to alter paths of evolution?
Transfer of genes between two species increases biodiversity
The removal of genes from a species decreases biodiversity
The transfer of genes within species increases biodiversity
The creation of new genes increases biodiversity
5
Which of the following is not a gene editing technique?
ELISA
Transgenesis
Gene therapy
CRISPR-Cas9
6
Evolutionary pathways and natural selection may be altered by which of the following?
Eating genetically modified organisms
Genome sequencing of humans
Using amino acid sequencing to find degrees of relatedness
Chemically killing fleas on animals
7
Which of the following is not a biotechnology?
Vaccines
Genetically Modified Organisms
Gel electrophoresis
Biosensors
