Information Conservationists are translocating 250 fish (taken at random) from a lake to a smaller pond that has recently been restored after a chemical spill, to repopulate the pond. Bewaringsbeamptes translokeer 250 visse (lukraak geneem) vanaf h meer na h kleiner dammetjie wat onlangs gerestoureer is na h chemiese uitval om die populasie daar te hervestig
Question 8 Complete Marked out of 1.0 The conservationists assume that the pond is ecologically similar to the lake after the restoration. If this is so, which micro- evolutionary process will probably have the greatest impact on allele and genotypic frequencies in the pond population (assuming the pond is completely isolated from the lake). Bewaringsbeamptes aanvaar dat die dammetjie ekologies dieselfde is as die meer, na die restourasie. Indien dit die geval is watter mikro- evolusionêre proses sal waarskynlik die grootste impak hê op allees- en genotipiese frekwensies in die dammetjie se populasie (aanvaar die dammetjie is heeltemal geisoleer van die meer) a. Migration Migrasie b. Assortative mating Sorterende paring c. Random genetic drift Lukrake genetiese dwaal d. Mutation Mutasie e. Selection Seleksie f. Inbreeding Inteling
Information After two days of the translocating the fish, conservationists determined that 40 fish have died due to being homozygous for a recessive allele at a detoxification gene that has made the fish susceptible to residual pollutants still left in the pond. Na twee dae sedert die translokasie van die vis, het bewaringsbeamptes vasgestel dat 40 visse dood is omdat hulle homosigoties was vir 'n resessiewe alleel by 'n ontgiftingsgeen wat die vis vatbaar gemaak het vir oorblywende besoedelingstowwe wat nog in die dam agterbly het. Question 9 Complete Marked out of 1.0 What is the allele frequency (q) of the susceptibility allele in the lake fish population? (round to one decimal) Wat is die alleel frekwensie (q) van die vatbaarheidsalleel in die meer populasie? (rond tot een desimaal) Answer: 0,4
Question 10 Complete Marked out of 2.0 What percentage of the surviving fish in the pond are carriers of the recessive allele? (round to two decimals) Watter persentasie van die oorblywende vis in die dammetile is draers van die resessiewe alleel? (rond tot twee desimale) Answer: 57.14 Question 11 Complete Marked out of 2.0 Considering the gene pool, what percentage of the zygotes produced by these translocated fish will be expected not to survive (assume there is random mating amongst surviving fish, they mate monogamously and all mate-pairs produce the same number of fertilised eggs)? (round to two decimals) Met betrekking tot die geenpoel, watter persentasie van die sigote wat deur hierdie visse geproduseer word sal verwag word om nie te oorleef nie (aanvaar die visse poor ewekansig, is monogamies en alle pare produseer dieselfde aantal bevrugte eiers)? (rond tot twee desimale) Answer: 22.40
Question 12 Complete Marked out of 2.0 After 5 generations (assuming the residual level of toxins remain the same), what will the allele frequency of the non-susceptible allele be in the pond population? (round to two decimals) Na 5 generasies (indien die vlakke van oorblywende toksiene konstant bly), wat sal die alleel frekwensie van die nie-vatbare alleel wees in die dammetjie se populasie? (rond tot twee desimale) Answer: 0.30
