B is for Cells
  • Why?

3
B is for Cells
  • A cell is the basic unit of a living thing.
    Cells carry the DNA of all living organisms. Most
    cells are so small that only a microscope can see
    them. Some living things are made up of only one
    cell, like bacteria or amoebas. Amoebas live at
    the bottom of ponds deep in the mud.

C is for Probability
  • Why?

5
C is for Probability . . .
  • In the science of genetics, probability is the
    chance of getting certain traits from your
    parents.

D is for Punnett Square
Why?...
7
D is for Punnett Square
  • A Punnett Square is a diagram that predicts all
    of the possible gene combinations from two
    parents.

In this diagram the yellow peppers are dominant
and the green peppers are recessive. Dominant
means that the yellow pepper has stronger traits
than the green pepper.

E is for Clone
Why?
9
E is for Clone
  • A clone is an exact genetic copy of a living
    thing. People have been cloning plants for over
    1000 years. In 1997, a small sheep named Dolly
    was the first living animal to be cloned.
    Scientists clone creatures to mass produce new
    special types of animals and plants. In the
    future some scientist even want to clone human
    beings. This is a very controversial subject. A
    possible reason for future cloning is to
    repopulate endangered or extinct animals.

F is for Chromosomes
  • Why ?

11
F is For Chromosome
  • Chromosomes are the carriers of genes. Humans
    have twenty three pairs or forty- six chromosomes
    and fruit flies have only 8. The more chromosomes
    an animal has the greater the complexity of the
    organism .

Matt
12
Layers of a Cell
Your body is made up of countless cells. Every
cell in your body has a nucleus and each nucleus
has 46 chromosomes. Every one of your
chromosomes contains the genes that make you
unique. In every single gene you can find your
DNA.
13
G is for Extinction . . .
  • Why ?

14
G Is For Extinction . . .
  • Extinction is when a species completely dies out
    and is gone for good .

Matt
15
H is for Crossbreed
  • Why?

16
H is for Crossbreed
  • Crossbreeds are hybrids of one species crossed
    with another. Although there are a lot of
    different kinds of crossbreeds, it is only
    possible to cross species that are in the same
    family. A human crossed with a dog would
    absolutely never work. This is not possible
    because of their extremely different genetic
    structures. Similar genetic structures are
    necessary for crossbreeding, for example, a
    poodle and a lab are crossbred to make a
    labradoodle.

L is for Species
Why?
18
L is for Species
A species is any living thing whether its an
animal or a human.
Paige
19
Classification of Life
Scientist organize all living things from the
largest group, which is life in general to the
smallest which is the species of any living
organism
The 5 classes of vertebrates are fish,
amphibians, reptiles, birds, and mammals. There
are also 6 classes of invertebrates as well.
20
M is for Genetics
Why?.....
21
M is for Genetics
  • Gregor Mendel was the scientist who
    discovered how genetics work. He discovered how
    they work by conducting a simple experiment on
    breeding pea plants.

Paige
22
Characteristics of pea plants observed by Mendel
  • 1. flower color is purple or white
  • 2. where flower attaches to stem 
  • 3. stem length is long or short
  • 4. seed shape is round or wrinkled
  • 5. seed color is yellow or green  
  • 6. pod shape is inflated or constricted
  • 7. pod color is yellow or green

23
O IS FOR DOMINANT GENESWhy?
24
O Is For Dominant genes
  • Dominant genes are able to override recessive
    genes . Dominant means stronger. For example,
    dark hair and dark eyes are dominant traits over
    blonde hair and blue eyes.

A smooth coat is a dominant trait for the
Chihuahua.

25
P is for traits
why?
26
P is for traits
  • Most of your traits are passed down from your
    parents. Your unique abilities, IQ, personality,
    and all of your DNA come to you through your
    parents. For example if your dad is an
    intelligent person and your mom is an intelligent
    person, more than likely youll be intelligent
    too. The genes from both of your parents are what
    makes you, you.

27
R is for AlbinoWHY?
28
R is for Albino
  • Albino genes are recessive. Recessive means
    weaker or less likely to happen. Albino means
    having a lack of color or pigment. For this
    snake to be an albino, the mother and father
    snakes both have to have the recessive genes for
    albino traits. A true albino has pink eyes and
    white fur or hair and no pigment in their skin.

Arik Hess
29
S is for Purebred . . .
  • Why?

30
S Is For Purebred . . .
  • Purebreds are creatures that only have parents
    of the same species. This German Sheppard is
    purebred . They will have consistent, replicable
    and predictable traits.

Matt
31
T is for Genes
  • Why?

32
T is for Genes
  • Traits are passed down in your genes. Genes
    carry your DNA. They are like a memory card that
    holds all of your personal traits. You could be
    like your Mom. You could be like your Dad, or
    like most people, you could be a little of both.

Alyssa
33
U is for DNA
Why?
34
U is for DNA
  • U is for DNA because every person has unique
    looks and different characteristics. No one
    person looks exactly like another unless they are
    cloned.

35
W is for Recessive . . .
  • Why ?

36
W is for Recessive . . .
  • Recessive genes are genes that are the weaker
    genes passed from parent to child. This albino
    lizard has recessive genes. Blonde and red hair
    are also passed on through recessive genes.
    Recessive genes are the rarest because dominant
    genes overpower them.

Matt
37
Interesting Facts!
  • Millions of cells have died and have been
    reproduced by the time you read this sentence!

Trillions and trillions of cells can make up huge
things, like whales, but other things like
bacteria can be made up of only a single cell.
Amoebas are microscopic living organisms which
consists of a single cell. Like all cells, it has
cytoplasm, a nucleus, and a cell membrane. It is
about 0.3 mm across and inhabits the mud at the
bottom of fresh water ponds. Although it is just
a single cell, it still grows, eats, produces
waste, and reproduces like all living organisms.
Identical twins start out as one egg and then
the egg splits into two.
A baby starts off from two cells that join
together and multiply again, and again, and again
growing into a human being made up of trillions
of cells!
Identical twins are close to being clones but
theyre not. Most twins have 50 similarity in IQ
and personality.
