Heredity and evolution
Basic 1
Genotype and phenotype
Slide 3 - Slide
Slide 4 - Slide
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 - Slide
Slide 6 - Video
Let's do a little inventory..
Which characteristics do you have?
Make sure you write down the results

Body cells, chromosomes, DNA
Slide 13 - Slide
Slide 14 - Slide
Chromosomes
Inside the cell nucleus are structures called
chromosomes
They are DNA strands and contain all of your
inherited characteristics
Slide 15 - Slide
Genes
A gene is a peice of DNA that contains the information for a characteristic
Slide 16 - Slide
Each body cell contains all the
genes but not all genes are active
Slide 17 - Slide
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 - Slide
Slide 19 - Slide
Slide 20 - Slide
Slide 21 - Slide
Phenotype = genotype + environmental influences
The phenotype changes…
…but the genotype doesn’t.
