WebThis is the simplest inheritance pattern possible, and most traits are NOT controlled this way. Other (more common) inheritance patterns include: Incomplete dominance: where heterozygotes have an intermediate phenotype in-between the two homozygous phenotypes. An example is petal color in four-o’clock flowers, where homozygotes are … WebPolygenic inheritance. Some characteristics are polygenic, meaning that they’re controlled by a number of different genes. In polygenic inheritance, traits often form a phenotypic spectrum rather than falling into clear-cut categories. Human skin color chart showing spectrum of skin pigmentation.
