Selective breeding,
inbreeding and
hybridization
By: Maayan and Alex N.
Selective breeding:
Mating 2 different
organisms to create a
new organism with
both traits of the
parents.
Advantages:
1. You get the
desired traits
that you
wanted.
Ex. Fur, products
made by the
animal, strength.
2.The animals can
be stronger. Ex.
More meat and
better tasting food.
Disadvantages:
*To much muscle growth can cause bad side effects.
Ex. Muscle growth is too fast and can cause heart failure.
*The animals might not turn out the way you wanted.
Maybe even worse.
Ex. The muscles in cows are stronger cause them to not
be able to give birth properly.
* In the pictures below, the animals have too much muscle to live normally.*
Inbreeding: Mating
organisms that are closely
related to each other
Advantages
1. Inbreeding organisms could produce
one single advance ,no flaws
organism. Ex. If some one would
want to create cows have healthy
genes and have it carry throw
children they would only bred with the
same cow.
2. If some one had created a chicken
with the gene to grow fast you
wouldn’t mate it with a chicken
without the gene other wise it would
mean no fast growing gene for some
chickens.
Disadvantages
1.Their will not be any difference between
the children and parents and
grandparents.
Ex. If some one would want to only have
purebreds then they would only mate with
other purebreds so their children won’t be
different.
2.If you there is only one type of dog
because of inbreeding then some one
would try and change it their won’t be any
other species
Hybridization: A genetically
modified animal that has only
desired traits by combing two
cells
Advantages
1.The new species could give
benefits to humans like farming or
less fatty meat.
Ex. If a cow could be combined with
a Ox it could work on the farm
and give milk.
2.If a dog had a bad gene you could
replace it with a new gene from
another animal.
Disadvantages
1.If you tried to combine a organism and
it turned out to be a bad combination
you would have to keep on testing wall
the animal suffers.
2. If you had a good turn out the animal
still mite not have a natural habitat
because it is two species.
