All the different parts are apart of the same question.
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. 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). a. a. Migration Migrasie b. Assortative mating Sorterende paring c. Random genetic drift Lukrake genetiese dwaal d. Mutation Mutasie e. Selection. Seleksie f. Inbreeding Inteling b. 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. C. What is the allele frequency (q) of the susceptibility allele in the lake fish population? (round to one decimal) d. What percentage of the surviving fish in the pond are carriers of the recessive allele? (round to two decimals) 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)? e. (round to two decimals) 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? f. (round to two decimals)
