IF THIS IS THE COMPLETE QUESTION WITH MULTIPLE CHOICE.
Two genes interact to produce various phenotypic ratios among F2 progeny of a dihybrid cross. Design a different pathway explaining each of the F2 ratios below, using hypothetical genes R and T and assuming that the dominant allele at each locus catalyzes a different reaction or performs an action leading to pigment production. The recessive allele at each locus is null (loss-of-function). Begin each pathway with a colorless precursor that produces a white or albino phenotype if it is unmodified. The ratios are for F2 progeny produced by crossing wild-type F1 organisms with the genotype RrTt.
9/16 Dark Blue 6/16 light blue 1/16 white
A) At least one copy of each dominant allele results in dark blue, at least one copy of either dominant allele produces light blue, and the absence of both dominant allele produces white.
B) If both dominant alleles are present, the result is dark blue. At least one copy of one specific dominant allele is required for light blue. If that dominant allele is not present, the result is white, regardless of whether the other dominant allele is present.
C) At least one copy of both dominant alleles results in dark blue; at least one copy of one of the dominant alleles also results in dark blue, but at least one copy of the other dominant allele produces light blue; and the absence of either dominant allele produces white.
MY ANSWER IS:
A) At least one copy of each dominant allele results in dark blue, at least one copy of either dominant allele produces light blue, and the absence of both dominant allele produces white.

Answer:
what is this I might know it:)
If the overall diversity of a population is measured that had gone through a recent bottleneck and then rapidly recovered its former population size, it would have a lower than expected diversity based on its population size.
<h3>What is Population Bottleneck?</h3>
- A population bottleneck is a situation where the population is substantially reduced. A variety of occurrences, such as an environmental catastrophe, the extinction-level hunting of a species, or the destruction of an organism's habitat, might result in the bottleneck.
- Due to the loss of many alleles, or gene variants, present in the initial population, the population's gene pool decreases as a result of the population bottleneck.
- The event has resulted in an extremely low amount of genetic variation in the remaining population, which indicates that the population as a whole has few genetic traits.
- When a population bottleneck occurs and there are alleles present, the residual population is more susceptible to genetic drift.
