selective breeding- selection certain
alleles
that code for the specific
trait
we want
best plants or animals are
bred
together
selective breeding- reduced
gene
pool
selective breeding- means best individuals are closely
related
(inbred)
inbreeding can mean that
inherited
disease are more prone and they are prone to
diseases
selective breeding means that the
population
as a whole are at more of a risk of
disease
genetic engineering- taking
desirable
characteristics from an
organism
to another
genetic engineering means to modify an organisms
genome
genetic engineering can treat
inherited
disorders
to treat
inherited
disorders you can use gene
therapy
(giving a person the healthy version of a gene)
its hard to treat inherited disorders due to:
difficult
to work as the faulty gene is in all
cells
its hard to treat inherited disorders due to: its hard to transfer new
gene
s to every cell
gene therapy is transferring a
gene
at an early stage of development and as they develop its passed down to other
cells
genetically modified crops advantages: more
fruit
, resistant to
disease
, more food for less
money
genetically modified crops disadvantages: we don't know how they affect our
health
, if they go into the wild they could alter
ecosystems
environmental impacts of genetically modified crops include: increased use of
chemicals
, reduced
biodiversity
