Chapter 23.3, Problem 2QTC
Summary Introduction
To analyze:
The difficulty in using genetic engineering to modify a trait determined by multiple gene interactions.
Introduction:
Genetic engineering is being used these days to modify existing traits in organisms. An example is gene therapy where the faulty gene in the organism is replaced by the right gene, reversing the harmful

Forward Genetics Analysis uses a variety of beneficial approaches to identify never before described genes.
For each of the following approaches or outcomes, briefly (maximum 2 sentences) discuss in your own
words, their purpose in Forward Genetics Analysis.
c) Mendelian ratios
d) Genetic screen
Genetic engineering utilized to create food sources has been said to be both like and unlike traditional breeding. One way it is different is:
It mixes genes from different individuals of the same or similar species
It involves whole organisms living in the field
It selects from combinations of genes that come together on their own
It mixes genes of different organisms such as viruses and crops, or spiders and goats
Each of the following describes a distinctive step in a genomic technology or an experimental design.
Match the term for each description.
An experimental design that looks at the
offspring resulting from an F2 cross, where
the parental generation have different
phenotypes. Then, look for correlation
between offspring phenotype and genotype.
The intensity of fluorescence in each spot
indicates the level of gene expression.
Only one fluorescent nucleotide is added,
which is complementary to the position of a
known SNP.

Explain three different applications: what it is, how it works and its benefits.arrow_forwardI believe that there are many good things that can come out of people getting to design their baby’s genetic material. But there are also many bad things as well. From the article by Bio medical about the pros and cons of having a designer baby it states that a pro is that this type of engineering can “ might help prevent genetic diseases such as Alzheimer’s, Huntington’s Disease, down syndrome, Spinal Muscular Atrophy, and many others”. I think that it is great that we could get rid of Alzheimer’s due to how destructive it can be to the people that suffer it. But I think the other diseases that it can eliminate is horrible due to them making our world a more unique place such as people with autism, Down syndrome. By doing this it could eliminate the whole population of people with disabilities community and make everyone “normal”. Another bad that I found in the article Ethics of designer babies which states that a major flaw for these babies is “designer baby technologies suggest…arrow_forwardIf you had the ability to do gene editing with ONE gene for the betterment of human kind, which one would you choose, and why?
