The presence of "S1" alleles in both gametes indicates that they were both derived from the same original cell during meiosis. The fact that these alleles are associated with different parental alleles (U1 in one gamete and S1 in the other) suggests that there was a crossover event between the two genes. The fact that the "P1" and "P0" alleles are present together in each gamete suggests that they were not involved in the crossover event and were instead transmitted together based on their relative position on the chromosome. This is consistent with a second-division segregation pattern, in which the alleles segregate into the gametes in a 2:2:2:2 ratio based on their relative positions on the chromosome.
