    Given are the statements regarding linkages of genes: (i) The strength of the linkage is determined by the distance between the 2 genes in question. (ii) The strength of the linkage is directly proportional to the distance between the two genes. The two genes are said to be linked when they fail to show independent assortment. Out of these statements:

    A)  all are correct

    B)  (i) and (ii) are correct

    C)  (i) and (iii) are correct

    D)  (ii) and (vi) are correct

    Correct Answer: C

    Solution :

                    Bateson in his experiment observed that a ratio of 7:1:1:7 was observed instead of normal independent assortment (1:1:1:1) and indicated that there was a tendency in dominant alleles to remain together. He also suggested that the strength of linkage will dependent on the distance between two genes in question. The two are inversely proportional. Linkage strength \[\alpha \frac{1}{Dis\tan cebetween\,the\,two\,gene}\]
