Things you need to know ....for AS 91157 Genetic Variation and Change (more genetics later)
- Genetic variation and change involves the following concepts:
- sources of variation within a gene pool
- factors that cause changes to the allele frequency in a gene pool.
- Biological ideas and processes relating to sources of variation within a gene pool are selected from:
- mutation as a source of new alleles
- independent assortment, segregation and crossing over during meiosis
- monohybrid inheritance to show the effect of co-dominance, incomplete dominance, lethal alleles, and multiple alleles
- dihybrid inheritance with complete dominance
- the effect of crossing over and linked genes on dihybrid inheritance.
- Biological ideas and processes relating to factors affecting allele frequencies in a gene pool are selected from:
- natural selection
- migration
- genetic drift.
