How do dominant genes and recessive genes affect taste?

Researchers have identified specific gene variants in the receptors that detect sweetness: TAS1R2 and TAS1R3. There is also high variation in the detection of bitterness. However, the story is more complicated than sweet taste, as we have 25 receptors that detect different bitter molecules

in situ hybridization has been widely used for research applications, including clinical cytogenetics, gene mapping, tumor biology and studies of chromosome evolution.

not sure but try c two haploid cells
