H21&25
Geography as bedrock for theory of evolution
Palaeontology = study of fossils (in layers of the earth (strata))
Catastrophism (Cuvier) “Species are more dissimilar in older strata; species abundance
changes due to immigration (no evolution) after catastrophes
Gradualism (Hutton) “Geological change is caused by slow processes”
Uniformitarianism (Lyel) “Same geological places take place now as did in the past”
Lamarckianism = “acquired adaptiations are transmitted to offspring” but that’s wrong, only
genetics are transmitted to offspring
Populations evolve by changes in allele frequencies caused by genetic drift, gene flow and
natural selection
The structure, diversity and adaptation of life is caused by processes that happened in the
past
Homology identity in a trait in two or more species via descent from a common ancestor
Les 2 Genetics
H12&13&14
- Define and explain the two laws of Mendelian genetics
- Define and explain mitosis and meiosis
- Define and explain different life cycle models
- Determine genotypes of individuals based on pedigrees
- Calculate expected offspring genotype frequencies in crosses given parental
genotypes
Mendals Law’s:
Law of segregation
Alleles segregate during gametogenesis and end up in different gametes
Law of independent assortment
Each pair of alleles segregates independently of each other during gametogenesis
So here is as example the purple and the white true breeding flower parents.
,Nu kwam er een verhaal over binomial distribution en een berekening waar ik niets van
snapte
,How does Mendals law work on mechanism ways?
Mitosis/Meiosis
Video’s online
, During meiosis 1 there can be recombination (crossing over), at the end of meiosis 1 there
are still 2 sister chromatids, at the end of meiosis 2 there is separation of the chromatids.
