natal genetic testing


Designer babies


Is behaviour genetically
programmed?


Cloning


an answer to organ transplants?


Of humans
-

is it right?


Values for the genetic age

Pre
-
natal tests


What do pre
-
natal test find out


on amniotic fluid


on cells from blastula (PGD)


Gross genetic anomalies,

e.g. Down’s, Edward’s,
Patau’s, Turner Syndromes

-

extra / missing chromosomes


Specific gene disorders,

but only if expected.

e.g. Huntingdon’s


Sex

Can we change

genes now?


It is possible to add genes non
specifically to the whole body.

(Fischer
-

Neckler Children’s Hos.
-

Paris.)

(rabbits that glow in the dark)


Its becoming possible to
direct specific genes to
chosen sites.


It may be possible to activate
human genes ...

e.g. for intelligence

Specific Genes


Ace gene for Athleticism


with the long form you can
climb to the top of Everest
without an oxygen mask


without it


17 genes for intelligence


identified in fruit flies


same in mice


not confirmed in humans


can activate in mice

Knowledge

is not free.


It places upon those who
know a burden of choice.


Knowledge can be used or
abused.


It can bring freedom, life and
happiness for many,


but it can also bring misery,
suffering and instant or
painful death

Choices


Just because we can do
something doesn’t mean
we should.


Who would get enhanced
abilities?


How would it change
society?


Would we be ruled by
genetically engineered
politicians
-

designed to be
the best (or most devious!)

Choices 2

apart from silly scare scenarios


Greatest pressure for
special babies would
come from those who
could afford it.


To give advantage to their
children.


To be able to say they had
one (or more) children
who had the best money
could buy.

Issues & Dangers


Purity of human genome


Long term effects


May not reverse as easily
as introduced.


Psychological effects on
person of being


manufactured


not normally produced

Issues & Dangers 2


Motive


to inherit


to save another


for immortality


to provide parts


to replace



relationships


who is your aunt


who is your
brother

Cloning Humans


Produces similar relationship
issues to the IVF abuse
described.

Hi Mum,

Other difficulties


Failure rates high


Dolly, 277 attempts


Copy Kitten, 87 attempts


Genetic Damage


Ageing


is it right to produce
identical human beings?


Does it abuse eggs?

Genetic Engineering

CCHS

16

Programmed
Behaviour?


Single genes for single
traits?
-

no (very rare)


Genes work together


Blueprint or Recipe


Genes contribute
potential, it’s up to you
what you do with it.

17

Cloning for
Transplants


Change DNA in egg and
grow.


A blastula is not a baby.


All cells identical
-

some
will become, liver, kidney,
skin, muscle etc.


Aim to direct grow into
specific cell types.


Not done yet.

Questions


When exploring an issue
need to find out the right
questions to ask. e.g.


Who is involved?


How is each affected?


Does it endanger individuals
/ everyone ?

Great benefits


Equal dangers


Will you think through the
issues?
