How do you explain the differences between the recombinant asci and the parental types answer?

When two genes are linked on the same chromosome; during meiosis, a crossover between these two genes often occurs, producing new recombinant types of gametes. The ratio between parental and recombinant types is always like this: m : n : n : m; where 'm' is parental types and 'n' is recombinant

where m parental types and 'n' is recombinant types, and 'm' > 'n'.
Parental type offspring have the same phenotype as the original parents,while recombinant offspring have a new phenotype not seen in either of the parents.
