An aquatic arthropod called a cyclops has antennae that are either smooth or barbed. the allele for barbs is dominant. in the same organism, resistance to pesticides is a recessive trait. make a "key" to show all the possible genotypes (and phenotypes) of this organism.

Lets consider the allele for barbs to be B and the allele for smooth to be 'b'. The possible genotypes and phenotypes will be

BB ( homozygous dominat barbs)

Bb ( heterozygous barbs)

bb ( smooth)

Lets consider the resistant allele to pesticide as 'r' and the non- reistant as 'R'.

The possible genotypes and phenotypes will be

RR (non- resistant)

Rr (non- resistant)

rr (resistant)

her next move would be to use agarose gel electrophoresis to separate the dna molecules of varying length and create a dna fingerprint.
