Genetic material
  • Genetic material is located in the nucleus of every cell.
  • Each nucleus has chromosomes  that contain DNA.
  • The genetic material is located in DNA molecules.
  • Nuclei of human cells have 46 chromosomes.

Slide 13 - Tekstslide

Chromosomes
The long thin threads of DNA are bundled together into  chromosomes (Fig. 1)

Chromosomes are located in the nucleus of every cell in your body (except red blood cells).
The chromosomes contain all information for all you hereditary traits. (Fig. 2)

Slide 14 - Tekstslide

Chromosomes

Slide 15 - Tekstslide

Body cells
The first 22 pairs of chromosomes are present in every human (called autosomes). 
The 23rd pair is special because they are not always the same. These are the sex chromosomes.
Sex chromosomes determine whether your genetic sex is male or female. 

Males have X-Y chromosomes
Females X-X chromosomes. 

Slide 16 - Tekstslide

sex chromosomes
Female:
Male:

Slide 17 - Tekstslide

Slide 18 - Tekstslide

genotype
complete set of inherited characteristics (genes/alleles, will get to that later ;-))

Slide 19 - Tekstslide

fenotype
Characteristics that are actually expressed (which show, which could also be 'inside' like a disease or a fast metabolism)

Slide 20 - Tekstslide

genotype
fenotype

Slide 21 - Tekstslide

Wat is genotype or fenotype? move traits A till H to genotype or fenotype. 
Genotype
Fenotype
a small nose
straight hair from birth
Piercings 
painted dark hair
a scar
Sarah can play the piano very well
calluses on your hands
blue eyes

Slide 22 - Sleepvraag

Slide 23 - Tekstslide

karyotype
- picture of all your 46 chromosomes
- 23 homologous pairs (1 from dad and 1 from mum)
- 22 pairs of autosomal chromosomes
- 1 pair of sex chromosomes XX or XY

Slide 24 - Tekstslide

fenotype = genotype + environmental factors

Slide 25 - Tekstslide

It runs in the family

Slide 26 - Tekstslide

so why do siblings differ?
