Mendel proposed the Principle of Independent Assortment based on results from which type of experiments? testcrosses dihybrid crosses complementation tests monohybrid crosses
1.)
The correct option is:
dihybrid cross,
The Law of Independent Assortment, as Demonstrated by Mendel's Experiment
The Law of Independent Assortment states that the mixing of characteristics in a dihybrid cross (a cross between two sets of traits) is unrelated to the mixing of traits in any other dihybrid cross. In other words, the formation of gametes involves the independent segregation of two sets of characteristics. The resulting dialogue is authentic to each pair of characters.
For the dihybrid cross, he used yellow spheres and wrinkled green seeds. His F1 generation seeds were uniformly round and yellow. In subsequent generations, self-pollination of the F1 generation's progeny produced four unique seed combinations. The phenotypic ratio of his inherited seeds was 9:3:3:1 for round yellow, round green, and wrinkled green.
The phenotypic ratios of the monohybrid cross, which were 3:1 for the round:wrinkled seed shape and 3:1 for the yellow:green colour, were likewise preserved in the dihybrid cross. He came to the conclusion that individuals' identities are not mixed with one another during the transmission of genes. His third law, the Law of Independent Assortment, was a direct result of this realisation.
