Island Populations
Naturally occurring geneflow comparing the mainland population to the Svalbard Reindeer is increasing or decreasing?
What is decreasing?
The group of people studied for this paper
Who are the Old Order Amish?
Names of Islands where platypus species diverved
What is Kangaroo Island and King Island
loss of genetic variation that occurs when a new population is established by a very small number of individuals from a larger population
What is Founder Effect
changes in DNA that result in having or being at high risk of developing genetic disorder
What is a Deleterious mutation
Low levels of genetic diversity and fitness could lead to...
What is extinction?
This is the effect that the paper was based off of that has led to potential mood disorder causing genes.
What is the founder effect?
Why do researchers see a seemingly high genetic diversity in Kangaroo Island Platypuses
What is no comparable data to analyze genome
Small head and body size, short extremities, ability to digest bryophyte's, seasonal regulation
What are morphological and physiological adaptations the Svalbard reindeer evolved to
reduced sized of a population due to an event, can lead to reduced genetic diversity as it allows the most best fit species to survive
What is Bottlenecked Population
Type of plant that was evolutionarily advantageous to be able to eat
What is a bryophyte?
These are the disorders that were studied within the paper, the disorders that potentially could stem from specific genes.
What are mood disorders?
Where were DNA samples taken from
Sourced Platypus from Rocky River and Breakneck River - DNA taken from web tissue
Leading consequence of founder effect
What is decreased genetic diversity
the reduction of the frequency of a deleterious allele, caused by an increased efficiency of natural selection prompted by interbreeding
What is Purging
Heterozygous allele combination is largely increased in this population
What are Mainland Populations (Figure 2)
This is the year that studies started on the population discussed in the paper.
What is 1970?
King Island or Kangaroo Island had greater decrease in expected heterozygous and what was the %
What is King island with a >90% reduction in expected heterozygosity compared to mainland
How quickly did the Svalbard deer adapt because of their reduced variation?
Over about 1000 generations (one new generation every 6 years)
The gradual movement of genes from one species into the gene pool of another, when there is some opportunity for hybridization between them
What is Genetic Introgression
Alleles in a low gene flow pool are...
What is fixed
These are the results of the paper
What is Old Order Amish-specific risk allele mood disorders are associated with depressive symptoms and cognitive performance?
What would come from sampling distribution issues when gathering platypus to study
What is a limitation?
Factor that most affects founder effect
What is genetic drift?
Loss of genome-wide diversity and evolutionary potential
What is Genome Erosion
