8 Inheritance Flashcards
Crossing Over
Sections of DNA are exchanged between homologous chromosomes
Independent Assortment
Different possible combinations of maternal + paternal chromosomes
Random Fertilisation
The combination of gametes that fuses together to form the zygote
(Race to the egg)
Autosomal Linkage
When 2 or more genes that are being inherited are located on the same non-sex chromosome
Hardy Weinburg Assumptions
Large Population
Mating is Random
No mutations occur
Isolated Population
No Natural Selection
Genetic Drift
Random changes in the gene pool of a population that occur by chance
Population Bottleneck
A series of events that dramatically reduces the size of a population + causes a severe decrease in genetic diversity
Founder Effect
Loss of genetic variation that occurs when a small number of individuals become isolated
Forms a new population with different allele frequencies
