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
The eye color of these people are.
A
Phenotype
B
Genotype
C
Phenotype en Genotype
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 30 - Tekstslide
Stripes, genotype or phenotype?
Slide 31 - Tekstslide
What's DNA a gene and chromosomes?
Slide 32 - Tekstslide
Genotype or phenotype?
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.
