Fig. 1. Expected selection intensity as a function of population size with one, two, four, and eight individuals selected per generation, assuming an underlying normal distribution of donor genome contribution among screened genotypes. (A) Donor genome contribution at nontarget loci after BC1 for different values of selectable population size (Nsl) and for the transfer of one or five target genes. (B) For this calculation, 10 chromosomes of 200 centimorgans (cM) (total genome size of 2000 cM) were considered with a DNA marker each 10 cM. The range of the sample size between vertical lines represents the most cost effective sample size.
