2 Causes of Gene Shuffling.
1-Chromosomes of homologous pairs move independently during meiosis.
2-Crossing over further increases number of different genotypes.
The number of times that allele occurs in the gene pool, compared to the number of times all other alleles for that same gene occur.
The process by which organisms with favorable variations reproduce at higher rates than those without such variations.
individuals with the more extreme form of a trait have a higher fitness than individuals with an average form.
individuals with either extreme variation of a trait have a higher fitness than those with the average form.
Survival of the Fittest
The more fit (adapted) the organism, the better chances they have to survive.
Why does the Founder's Effect occur most likely after a Natural Disaster?
The organisms could be seperated by the natural disaster, forcing the animals to adapt to their new environment.
5 conditions to maintain genetic equilbrium.
2-Very large population
3-no immigration or emmigration
5-No Natural Selection
2 populations are capable of interbreeding but do not understand each others courtship rituals.
