NEET Biology question
Mendel could not find out linkage because I. some genes are linked but they are too far apart for crossing over to be distinguished from independent assortment; II. linked genes, were never tested for the same time in same cross; III. all seven genes, were present on the same chromosomes; IV. all seven genes were present on 4 chromosome but they were present far apart. Find out the correct option
Solution
Although some of Mendel's 7 studied genes were in fact located on the same chromosome (among the 4 chromosomes they collectively occupied), they happened to lie far enough apart that frequent crossing over made them behave, statistically, just like unlinked genes assorting independently (statement I); additionally,
