HOMEWORK: Read and notes for chap. 11.2.
Objective: I will understand how
genetic information passes from
one generation to another.
Mendel and the discovery
of genetically transferred
traits.
Gregor Mendel realized inheritance
patterns first.
Why did he cut off the stamens of the purple
pea plant?
P = Parental
F = “filial” = son
He learned that certain traits
were DOMINANT over others.
He found 7 traits that were
dominant
Mendel determined this WITHOUT
understanding genetic makeup.
Today we know that we receive ONE
allele from each parent On our
genes.
Alleles = alternative
forms of a gene
matching one another
on homologous
chromosomes.
Using mathematics, he realized he
could determine the “genotype” of an
organism using a Punnett Square
He used SYMBOLS of Capital
letters to represent Dominant traits
like “B” and lower case letters to
represent recessive traits like “b”.
Since we get ONE from each parent
we can write them:
BB
Bb
bb
NOTE: 2 letters = 1 from each
parent
Notes 11.1
• PP and pp are known as Homozygous or
having two alleles that are the same.
• Pp is known as Heterozygous or having
two alleles that are different.
• Dominant Allele – An organism that has
at least one dominate trait will exhibit that
form of the trait. (Ex. BB, Bb – Exhibit B)
• Recessive Allelle – exhibit only when
both allelles are recessive. (Ex. bb –
Exhibit b)
Genotype
• Possible combinations: AA, Aa, aa
• It is how the genes combine together.
Phenotype
• It is the physical characteristics
based on the genes.
• It is how the genes make you look.
P1 - parental generation.
 F1 - first filial generation.
 F2 - the second filial
generation.
 Filial (son or daughter)

the genotype and phenotype

HOMEWORK: Read and NOTES 11.4 for
Monday.
Objective: I will understand exceptions to
Mendel’s principles.
Exceptions to Mendel’s principles:
Incomplete Dominance – some allelles are
neither dominant nor recessive. (Ex. Red
flowered and white flowered plants produce
pink-colored flowers.)
Codominance – Phenotypes produced by both
alleles are expressed.
(Ex. Both colors appear like a speckled
chicken-black and white.)
Multiple Alleles – gene with more than two
alleles. (Ex. Rabbits coat color is determined
by a single gene that has at least four
different colors.)(Another example is human
blood type.
Polygenic Traits – traits controlled by two
or more genes. (Ex. Human skin color)
Environment – environmental conditions
can effect phenotype. (Ex. Certain
butterflies born in the spring have
different color wings than those born in
the summer.)
