Biology 1
- Genes
- Made up of 2
sets of 23 alleles
- You can show
inheritance
through punnett
squares
- Chromosomes
- Recessive
- You need two copies
for it to affect you
Annotations:
- Needs a copy of two of the alleles for it affect you one from the male and one from the female
- You need two copies
for it to affect you
- Dominant
- Only need one copy
for it to affect you.
Annotations:
- only needs one copy of the allele for it affect you either needs it from the female or male
- Only need one copy
for it to affect you.
- Recessive
- Made up of 2
sets of 23 alleles
- Genetic Diseases
- Huntington's Disease
- This is a dominant disease;
causing in memory loss, early
death...
Annotations:
- (dominant allele)
- This is a dominant disease;
causing in memory loss, early
death...
- Cystic Fibrosis
- This is a recessive disease;
causing thick mucus in the body
which affects a number of
organs, particularly the lungs
and digestive system
Annotations:
- (recessive allele)
- This is a recessive disease;
causing thick mucus in the body
which affects a number of
organs, particularly the lungs
and digestive system
- Huntington's Disease
- Variations
- The differences between
individuals of the same species
- Twins
- Twins that look the same but different
Annotations:
- ask teacher for more detail.
- Twins that look the same but different
- Twins
- Genetic inheritance
- The things you inherit
from your parents
- Diseases
- Eye colour
- Natural hair colour
- Ear lobes
- Weight, Height, Hair,
Intelligence
- Diseases
- The things you inherit
from your parents
- Environmental
- The things that you gain as you
grow up from the places you live or
the way you are raised.
- Un-natural hair colour
- A tan
- Any scares
- Weight, Height, Hair,
Intelligence
- Un-natural hair colour
- The things that you gain as you
grow up from the places you live or
the way you are raised.
- The differences between
individuals of the same species
- Cloning
- Clones are organisms that are exact
genetic copies. Every single bit of
their DNA is identical
- Clones can happen naturally-
identical twins are just one of
many examples
- In nature, twins form very early in development when the embryo
splits in two. Twinning happens in the first days after egg and
sperm join, while the embryo is made of just a small number of
unspecialised cells. Each half of the embryo continues dividing
on its own, ultimately developing into separate, complete
individuals. Since they developed from the same fertilized egg,
the resulting individuals are genetically identical.

- Clones can be made using
modern cloning technologies
- Artificial embryo twinning
- Artificial embryo twinning uses the same approach as
natural twinning, but it is carried out in a Petri dish instead
of inside the mother. A very early embryo is separated into
individual cells, which are allowed to divide and develop
for a short time in the Petri dish. The embryo's are then
placed into a surrogate mother, were they finish
developing. Again, since all the embryo's came from the
same fertilized egg,they are genetically identical.
