Lecture 1 : Biodiversity Flashcards
Biodiversity
the variety of life, in all of its manifestations
Components of biodiversity
- genetic diversity
- organismal diversity
- diversity of species
- human cultural diversity
- linguistic diversity
Genetic diversity
- genome size ( amount of DNA in chromosomes )
- number of genes
- there is no connection between genome size and number of genes
Genes exist in multiple forms called
alleles
Which form of diversity is considered to be the most vital form for evolution
genetic diversity
True or false, smaller populations have greater genetic diversity than large ones
False, large population have greater genetic diversity
True or false, stable populations will have greater genetic diversity than those that wildly fluctuate
True
True or false , populations in the center of the species’ geographic range often have more genetic diversity than those at range margins
True
Genes can be vulnerable or resistant to
Temperature, Natural disasters, Disease
Organismal diversity
-Measures how rich a species is ( number of species )
