Key Topic
Gene Frequency Example tongue rolling Test on Friday

Evolution of blank

·      Vocab development

Gene pool

Genetic drift

Allele

Allele frequency

Hetero and homozygous

Phenotype

Genotype

Punnet square

 

·      Allele is a symbol to show a trait (ie tongue rolling) Hardy Weinberg formula
·      Definition for evolution is

A change in gene frequency in a population.

How do you find this out?

·      Tongue rolling explain (use the board)

·      An allele is a letter to signify the presence or lack of presence of a trait.

·      Populations include a variety of traits. Some can be detrimental.

·      The HW equation can be used to predict the affect of frequency within a population.

Big Point

 

The sum of P and q always one to denote the complete population

·      Terminology

P is a letter to denote having the trait.

Q is a letter to denote not having the trait.

·      Punnet squares show probability.

·      (P+Q) squared is

P (squared) +2PQ and Q(squared)

 

 

·      Why use the formula genotype
·      Tricks to solve problem.

a)   format

b)   sample question

·      Careful about purebred and codominant and incomplete dominance Can you use a punnet square or a work sheet?

What are the five conditions that create HW in equilibrium?

 

Consider the following

 

If population is in equilibrium, will evolution be occurring?

 

How would allele frequency change if an allele is being favoured?

 

What would be the affect of changes in birth rate, migration,

 

How could HW Equation be linked to Sickle cell anemia

 

Options for learning how to use formula

a)   plug and play

b)   problem solve with partners

c)    work with problem sheet

Take home?

Change in gene frequency

How that occurred?
