A3.1 HL

sl - biological species concept

to be considered as the same species, they need to breed togetger and produce fertile offspring

parthenogenesis - asexual reproducing

syntesize a baby as a virgin

binary fision - asexual reproducing

bacterias reproduce by itselves by that

vegetative propagation - asexual reprodusing

continue to grow - strawberries

vertical gene transfer

transferring genetic matierial to the next generation

horizontal gene transfer

transfering genetic matierial to another bacteria that already exists (same generation). this way the organism can have mixed genes from different species. mosaic of genes from fifferent sources. not only bacteria to bacteria

xenologs

jumping genes

interspecific hybrid

combination of two different species

why hibrids can not have offsprings?

difficult production of gametes

dna barcode

a short sequence of DNA inside an organisms’ cells that can be used to quickly indentify the species

BIN

barcode indentification number

eDNA

enviromental DNA

adventages of eDNA

time efficient, less distruption

disadventages of eDNA

does not indicate number, does not idicate dead or alive, chemicals in a sample can interfere with process

bioindicators

these organisms are so sensitive to certain types of pollution, when presrnt=pollution absent, when absent=polution present
