1. What we will do What we will learn 10N 28 Poutū-te-Rangi 2017
Quick quiz and preliminaries
How to start well
Revisit genetics intro: dominant, recessive, allele, heterozygous, homozygous, punnett square AND introduce genotype and phenotype
Useful definitions for the buzzwords in this topic
See why Cystic Fibrosis happens and what being a “carrier” means
How genetic diseases affect humans
Use Punnett squares to compare CF scenarios.
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

12. Lived from 1822 to 1884 in the Czech Republic
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.

14. 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.
