Conservationists are translocating 250 fi sh (taken at random)
from a lake to a smaller pond that has recently been restored after
a chemical spill, to repopulate the pond. After two days of
the translocating of the fish, conservationists determined that 40
fish have died due to being homozygous for a recessive allele at a
detoxify cation gene that has made the fish susceptible to residual
pollutants still left in the pond.
QUESTION:
(A) 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)? (Two decimals)
(B) After 5 generations (assuming the residual level of
toxins remains the same), what will the allele frequency of the
non-susceptible allele be in the pond population? (Two
decimals)
