Some Genes Are Dominant

Using several animated sequences, this interactive activity adapted from the Dolan DNA Learning Center demonstrates the principle of dominance, which is fundamental to modern genetics. By crossing two pea plants, each pure-bred for a given trait like pea color, we learn why only the dominant trait—in this case, yellow pea color—appears in any and all offspring. We also learn why some offspring in subsequent generations exhibit the recessive trait—green—even though this may not have been apparent in the previous generation.

This media asset was adapted from Some genes are dominant. by Cold Spring Harbor Laboratory, Dolan DNA Learning Center.
