Slide 2 - Tekstslide

Unit 5 
Heredity and evolution

Basic 1 
Genotype and phenotype

Slide 3 - Tekstslide

Slide 4 - Tekstslide

After today

You can explain the difference between genotype and phenotype
You can explain that cells only use the hereditary information that they need

Slide 5 - Tekstslide

Slide 6 - Video

Let's do a little inventory..
Which characteristics do you have?
Make sure you write down the results

Slide 7 - Tekstslide

Slide 8 - Tekstslide

I can roll my tongue
YES
NO

Slide 9 - Poll

Which hand do you write with?
LEFT
RIGHT
NO PREFERENCE

Slide 10 - Poll

Hand clasping?

Slide 11 - Poll

Slide 12 - Tekstslide

Body cells, chromosomes, DNA

Slide 13 - Tekstslide

Slide 14 - Tekstslide

Chromosomes
Inside the cell nucleus are structures called chromosomes
They are DNA strands and contain all of your inherited characteristics

Slide 15 - Tekstslide

Genes
A gene is a peice of DNA that contains the information for a characteristic 

Slide 16 - Tekstslide

                                                        Each body cell contains all the 
                                                   genes but not all genes are active

Slide 17 - Tekstslide

To inherit = to receive a characteristic from an ancestor by genetic transmission. 

  • Genotype = the information for an organism’s complete hereditary characteristics
  • Phenotype = visible and invisible physical characteristics of an organism

           Phenotype = genotype + environmental factors. 

Slide 18 - Tekstslide

Slide 19 - Tekstslide

Slide 20 - Tekstslide

Slide 21 - Tekstslide

Phenotype = genotype + environmental influences
The phenotype changes…

…but the genotype doesn’t.

Slide 22 - Tekstslide

If you look at this persons hair..
A
Phenotype
B
Genotype
C
Phenotype en Genotype

Slide 23 - Quizvraag

Slide 24 - Quizvraag

Put in the correct order,
from small to big.
A
cell - chromosome - DNA - gene
B
gene - chromosome - DNA - cell
C
gene - chromosome -cell - DNA
D
gene - DNA - chromosome - cell

Slide 25 - Quizvraag

Which one is correct?
A
Phenotype = genotype + environment
B
Environment = genotype + phenotype
C
Genotype = phenotype + environment

Slide 33 - Tekstslide

Slide 34 - Tekstslide

After today
You can explain how each of the parents provides 50% of the chromosomes.
 You can say how the sex of a human is determined by sex chromosomes.
 You can explain how sexual reproduction causes variation in genotypes.
