-How did you inherit characteristics from your parents?
-Why do some inherited characteristics not show?
-What are chromosomes?
-Why do siblings look similar to their parents and each other?

Slide 9 - Tekstslide

- inheriting characteristics from parents
- how gender is determined
- how chomosomes, DNA and genes are related
- how to determine characteristics of offspring from a given combination of parents
- how to read a pedigree
Phenotype
  • All your characteristics = phenotype
  • Phenotype is a combination of: genotype (DNA) and influences from your surroundings


Examples:
  • Hair colour
  • Weight
  • Voice
  • Lung capacity
  • Build of your muscles

  • Blood pressure
  • etc

  • Phenotype = set of characteristics that are seen/expressed. 

Phenotype = genotype + pattern of gene expression + environmental factors. 
We will learn more about this later this chapter

Human cell

There are 23 chromosomes in a female egg cell.
In a male sperm cell are 23 chromosomes present


Egg + sperm = a fertilized egg cell has 46 chromosomes







What are chromosomes?

Slide 15 - Tekstslide

What are chromosomes?

 homologous pairs.
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
