NEET Biology question
Which of the following is true about linkage: I. It is phenomenon in which more recombinants are produced in F2-generation; II. More parental combination are produced in F2-generation; III. Genotype which are present in F1 hybrid reappear in high frequency in F2-generation; IV. It is a phenomenon in which two chromosome are linked.
