What main idea did Mendel understand from a dihybrid cross?
Answer and explanation
Correct answer: Information for two different traits can separate independently
A dihybrid cross follows two pairs of contrasting traits at the same time. Mendel’s results showed that, when the genes are not linked, the inheritance of one pair can occur independently of the inheritance of the other pair. This is the principle of independent assortment, so A is correct. Traits do not always travel together, and Mendel’s work supports inheritance of genetic factors rather than acquired traits.
