Expert Answer
(i) The law of independent assortment states that the alleles of different characters located in different pairs of homologous chromosomes are independent of one another in their segregation during gamete formation and in coming together into the offspring by fertilisation, both processes occurring randomly.
(ii) (a) Crossing over: Crossing over influences linked genes. As a result, 50% recombination is obtained in the test cross progeny.
(b) Linkage: It influences recombination which is less than 50%.
