Alleles will either be dominant or

• recessive

• the majority

• all alleles are dominant

The term incomplete dominance refers to what characteristic?

• Both dominant traits being expressed, as seen in flowers where red and white are dominant colors. The offspring will be both red and white.

• Both dominant traits being expressed, as seen in flowers where red and white are dominant colors. The offspring will be a blend of the two, usually pink.

• This occurs where an organism chooses what dominant trait it wants.
