Which of the following phenomena is a consequence of Independent Assortment?View Available Hint(s)Which of the following phenomena is a consequence of Independent Assortment?Pure breeding plants, when mated with each other, produce completely homozygous offspring.For any gene displaying complete dominance, heterozygous individuals exhibit the dominant phenotype.Smooth seed trait is dominant to wrinkled seed trait in peas.The phenotypic ratio among phenotypes produced from an F1 X F1 dihybrid cross is 9:3:3:1.

Answer 1

The phenotypic ratio among phenotypes produced from an F1 X F1 dihybrid cross is 9:3:3:1.

Step-by-step explanation:

The law of independent assortment is Mendel's fourth postulate which states that alleles of different genes are independently of one another assorted into gametes during meiosis. So, if we observe two traits, for example pea color (gene A) and pea shape (gene B), the alleles A and a will separate independently of alleles B and b. Mendel has shown in his experiments (with dihybrids-heterozygous for both genes e.g. AaBb) that there are four different categories with the phenotypic ratio 9:3:3:1.
