1.	Study the figures given below and answer the question.Identify in which of the crosses the strength of linkage between the genes is higher. Give reasons in support of your answer.
Answer» Cross A, because they are tightly linked / due to close physical association / they are closely located. Detailed Answer : Strength of linkage between genes is higher in cross A than that of cross B because the two genes YW are located closely on the same chromosome. Whereas in case of cross B the genes w and m are located far apart on the same chromosome. Therefore, in the latter cross the chances of recombination are higher due for crossing over because lesser the distance between genes greater the strength of linkage.
