calculating biodiversity Flashcards
(11 cards)
define an allele
- a version of a gene
define a locus
- the position of that gene on a chromosome
define polymorphic gene locus
- a locus that has more than 2 alleles
the more species present …
the richer the habitat
what is habitat with high species evenness going to look like ?
- more even numbers of individuals in each species
what is a habitat with low species evenness going to look like ?
- one which individuals of one species outnumber all the others
what gives an indication of genetic diversity within a population ?
- the number of variations of a gene
what has a lower genetic diversity compared to the other in terms of eye colour ?
homozygous individuals for eye colour have a lower genetic diversity than heterozygous individuals
what can heterozygous individuals pass on compared to homozygous individuals ?
- both the B and b allele to the next generation
- can only pass one allele
what can be used to calculate the genetic diversity ?
proportion of polymorphic gene loci = number of polymorphic gene loci / number of gene loci
