Illustration showing Mendel's Law of Independent Assortment, or Inheritance Law . This law states that separate genes for separate traits are passed independently of one another from parents to offspring. Shown here is an example of cross breeding garden peas (Pisum sp.). Round yellow seeded and wrinkled green seeded parents produce a first generation (F1) with round yellow seeds. Self-pollinating these produces a 9:3:3:1 ratio of round yellow, wrinkled yellow, round green and wrinkled green seeds (F2). Each parent has a pair of alleles for seed colour and another pair for shape, and in reproduction each randomly provides an allele from each pair. Alleles for yellow seeds and smooth seeds are dominant over the other two. | |
