What we will do
What we will learn
Quick quiz and preliminaries
Revisit genetics intro: dominant,
recessive, allele, heterozygous,
homozygous, punnett square
AND introduce genotype and
phenotype
How to start well
Useful definitions for the
buzzwords in this topic
See why Cystic Fibrosis happens
and what being a “carrier” means
Use Punnett squares to compare
CF scenarios.
How genetic diseases affect
humans
How being a “carrier” can be
passed along
If time, do a Punnett square on
Jimmy and Jeannie
How Punnett squares works
with dog breeding

Vas Deferens (Sperm
Tube)
FUNCTION
Lived from 1822 to 1884 in the Czech Republic. He investigated
INHERITANCE (which is info passed on from one generation to the
next).
He planted peas and did lots of observations and measurements
to investigate TRAITS or CHARACTERISTICS.
His work – plus that of some others – showed that there is a
reason that all living things have two copies of each gene.
An ALLELE is one of TWO possible version of a gene. One version
is DOMINANT (its message is stronger) and one version is
RECESSIVE (its message is weaker). The dominant message will
come through unless BOTH copies are recessive.
Word
Meaning
Dominant
An allele which controls what an organism looks like. (The more
powerful message of the two possible)
Recessive
Only shows up when there are two of these. (The weaker of the two
possible – so it shows up when the other one is missing)
Homozygous
Containing two identical forms of the same gene. (Both dominant or
both recessive)
Heterozygous
An individual containing two different forms of the gene.
Allele
Different forms of a gene.
Genotype
The genetic make-up of an individual. The “type-o’-gene”. i.e. is it
heterozygous, homozygous dominant or homozygous recessive?
Phenotype
The physical characteristics of an individual. “Phenotype” is “the TYPE
of PHENOmenon”. i.e. – what shows up.
