he experimented with and what he
discovered about traits.

-400A
He worked with pea plants and
traced traits for three
generations. He used the
mathematics of probability to
discover dominant and
recessive traits.
You cross two parent
pea plants:
One with yellow pods
One with green pods. In the 1st
generation all the pods are green, but
In the 2nd generation three pods are
green and one yellow. Tell me which
trait is dominant and which recessive,
be sure to explain why this occurs.
3-500
Green pod dominant,
yellow recessive. We
know that recessives will
occur 25% of the time
when crossing two
heterozygous parents. We
see the 25% occurrence
in the 2nd generation.

genotype and

They are contrast because genotype
is the genes you have, and phenotype
is the physical expression of your
Genes. They compare in that your genes
(genotype) is what makes you look a
certain way (phenotype).
Ex. TT genotype = tall phenotype.

Is awesomeness a genetic trait that I can
Give to Lilly?

We can use Punnett squares to
find the probability of a trait being
passed from parents to offspring, so
traits are not random.

disorders.
Is this a dominant disorder or sex-linked,
explain how you know.
5-500
Sex-linked. Sex-linked
diseases are caused by a
recessive gene on the X
chromosome. This means
that ONLY females will show
as carriers. With dominant
disorders male and females
can carry.

Clone rights: dont use them as spare parts,6-300A
must be protected, but what about
organs that we have two or more of?
twins: Using cells from a healthy twin to one who is ill. same to do in a clone
Underground cloning: no rules if no one knows.
Cloning: has negative moral implications.
A large number of clones will die before it works.
Extra pressure if you were Einstein's clone.
People could steal your dna(blood, nail or hair) and use it to make a clone.
A clone WILL NOT bring back a loved one! not the same person.
Would a clone taken from an adult live only for a short time? say 33 year old clone
will only live 30 more years even though your clone is a baby.

The A alleles are for acid breath. Dominant is acid
breath recessive is lack of acid breath.
The C alleles are for claws. Dominant is claws and
recessive is lack of claws.
