Answer:
Linkage.
Step-by-step explanation:
The Mendel's second law is also known as the law of independent assortment. According to this law, the assortment of two different genes are independent of each other.
The law of independent assortment is applicable only when the two genes are on the different chromosomes. If the two genes are on the same chromosome, they undergo the process of linkage and do not assort independently. The linkage will result in the formation of recombinant progeny.
Thus, the correct answer is option (c).
