predict the genetic composition of gametes derived from tetr

predict the genetic composition of gametes derived from tetrads of inversion heterozygotes where crossing over occurs withing a pericentric inversion

tetrads means 4n=82 and on its inversion we will have PpPp phenotype which means genetic composition will have 25% each of the genes as the 100% will be divided into 4n making it 25 % each genes.
