2. Genetics is the science of genes, heredity, and
variation in living organisms.
Genes can be found in any living thing.
Genes describe what traits you might have.
You can identify traits by using a punnett
square.
3. Mitosis
Asexual Reproduction
The process of dividing
2 cells forming a replica.
Occurs in only
humans, animals, plants
, and fungi.
Meiosis
Sexual Reproduction
The process in which
the number of
chromosomes are
reduced by half.
Occurs in all organisms
4. Gregor Mendel was the founder of genetics.
He discovered genetics by doing an experiment
on pea plants. He studied the traits that each
pea plant had including seed shape, pod
color, etc. This helped him come to the
conclusion that each plant had a different types
of alleles.
5. A genetically modified organism is one whose
genetic material has been altered by genetic
engineering.
Transgenic plants have been engineered for
scientific research to make different crops and
different colors in plants.
Some crops that are genetically modified have
traits that make them resistant to insects.
Some crops that are on there way to being sold
can live in environmental conditions outside
the type of plants native range.
6. The evolution of plants has caused a higher
amount of levels of complexity.
Land plants have evolved from algae from as
early as 510 million years ago.
Leaves today are an adaptation to increase the
amount of sunlight that can be captured for
photosynthesis.
It is believed that plants used to be spiny to
protect themselves from herbivores.
