One of Mendel’s experiments was repeated by crossing a red variety of pepper with that of a yellow variety which produced all red offspring. The red offspri...

The yellow color in this case can be said to be recessive to red. This is because when the red variety of pepper was crossed with the yellow variety, all the offspring produced were red, indicating that the red trait was dominant. When these red offspring were self-pollinated, they produced both red and yellow peppers, indicating that the yellow trait was present but hidden in the previous generation. This suggests that the yellow trait is recessive to the red trait. In genetics, dominant traits mask recessive traits, and recessive traits only express themselves in the presence of two copies of the same gene (homozygous recessive) or in combination with a dominant allele (heterozygous). Therefore, the yellow pepper in this case is homozygous or heterozygous for the recessive trait.
