What does independent assortment mean in a Mendelian cross involving two traits?
Answer and explanation
Correct answer: Inheritance of one trait can be independent of inheritance of another trait
The governing concept is Mendel’s law of independent assortment. During gamete formation, allele pairs for different traits can separate and arrange independently, provided the genes are not linked in a way that prevents this pattern. In a dihybrid cross, this produces combinations such as round-yellow and wrinkled-green as well as new combinations. Therefore A is correct; B states the opposite, while C and D confuse inheritance with reproduction.
