Given below are a few statements on concepts of molecular breeding.
A. Correlations between quantitative traits can be because of pleiotropic effects of the same gene and/or genetic linkage of genes associated with the traits.
B. In a Recombinant Inbred Line (RIL) population, genetic segregation of both dominant and codominant markers occurs in a 1 : 1 ratio.
C. Near isogenic lines (NILs) can be produced by repeated backcrossing of the F1 to a recurrent parent.
