Independent Assortment The principle of independent assortment states that genes for different traits segregate independently during the formation of gametes. Mendel crossed plants with contrasting characters and tye their offspring. Copy the chart below in your notebook. What is the probability of a homozygous recessive offspring?

Auth with social network: The F2 generation gets a new combination of alleles: Mendel drew two conclusions: A trait is a specific characteristic that varies from one individual to another. At the end of meiosis, the number of chromosomes in gametes is half the number of chromosomes in body cells. Lesson Summary The Experiments of Gregor Mendel The delivery of characteristics from parents to offspring is heredity. The principle of dominance states that some alleles are dominant and others are recessive.
