Question

Modeling selection. You are studying the federally endangered green pitcher plant Sarracenia oreophila) in Tennessee. Assume that there are two different alleles for chlorophyll a, the normal (wild-type) allele indicated by a t, and a mutant form (indicated by a c) that yields a slightly different pigment. Also assume that the wilcd type allele is completely dominant to the mutant allele and that homozygote mutants only survive ½ as frequently as the wild-type forms. Finally, assume that the initial allele frequencies are: + = 0.6 and c= 0.4. Given these assumptions, A) what is the selection coefficient for the recessive condition and B) what would you expect the frequency of the mutant allele to be after one generation?

Explanation / Answer

the green pither plant is also known by its scientific name called Sarracenia oreophila. it is a carnivorous plant . it has highly modified leaves in the form of pitcher that act as pitfalls trap for prey.the narrow pitcher plants are tapered tubes which are rises upto 75 centimeters from the ground.with a mouth 6 -10 cm in it circumtances.it is having the more risk to be an endangered species of it kind in the present time.

like the other pitcher plant it is also having the trap system in which it trap the insects in the tubular rolled leaves which stored digestive juice at the buttom of the tube.

A) the selection procedure and the cofficient will be .015

B) and the frequency of the mutant is 58.
