Steps of Genetic Modification using recombinant DNA technologyGenetic Modification -Occurs when humans manipulate an organism’s genetic make-up.1.Identify the gene for the desired trait and extract
it from the DNA.2.Insert this gene into a bacteria cell’s genetic
material and let the bacteria reproduce.3.Remove the modified genetic material from
many bacteria cells and insert it into a plant cell or zygote.
4.Allow the organism to grow and develop and produce new offspring that carry the trait.
All cells of the new offspring should have the desired trait.

Natural variation from sexual reproduction,mutations, and gene shuffling means that not everyone in a species is identical.
In artificial selection humans choose whosurvives and reproduces.

1.Living things over reproduce:More babies are born then survive.
2.There is variation among the offspring.gene shuffling ( sexual reproduction)
mutations3.Struggle to survive (competition)4.Those that survive have the chance
to reproduce.

Those that have the genetic traits to survivein that environment reproduce and make thenext generation.
Individuals that survive and reproduce are said to be “fit” or exhibit “fitness”

1. More offspring are created than survive.
2. There is variation among the offspring,Due to sexual reproduction & gene shufflingand mutation
3. There is a struggle to survive. (Competition)
4. The individuals that are best suited to the Environment (fit) survive and the future generations look like them.

Bacteria, which reproduce asexually, can use a process called lateral gene transferin which some genes are swapped (like trading cards) between 2 individuals. Thisprocess gives bacteria more variety and promotes antibiotic resistance in bacteria.

Conditions that promote evolution.
•nonrandom mating (choosing who to mate with)
•small populations
•immigration or emigration
•mutations
•natural selection
One or more of these usually occurs in real populations.

How can new species come from existing species?
Reproductive Isolation gives rise to new species.
What are 3 mechanisms that can preventindividuals from the same species from breeding with each other?

Behavioral Isolation: Behavior is a turn off.
Geographic Isolation: They cant get togetherdue to things like distance, bodies of water, mountain ranges, and deep valleys.
Temporal Isolation: Work different shifts and don’t get to meet each other.

Behavioral Isolation: Behavior is a turn off.Eastern meadowlarks don’t respond to western meadowlarks songs.
Geographic Isolation:They can get together
Temporal Isolation:Work different shifts.

Eventually their DNA is so different if individuals fromthe different populations meet and try to reproduce they can not or haveunfertile offspring.
As populations of the species stop interacting their populations experiencedifferent selective pressures causing a shift in the common phenotypes.
