Example sentences for: backcross

How can you use “backcross” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • A mapping population consisting of 1,308 backcross (BC

  • For a normally distributed phenotype, 75 parameter combinations for the backcross were examined.

  • Using restriction-length-fragment polymorphism (RFLP) and RFLP-derived cleaved amplified polymorphic sequence (CAPS) markers (Figure 1) based on previously published tomato genetic and RFLP maps [ 8], initial studies mapped the dgt locus to a region of around 0.8 cM near the bottom of the long arm of tomato chromosome 1. Of 1,308 backcross (BC 1 ) individuals screened, 10 plants were determined to be recombinant between markers TG269 and CT190, whereas no plants were found to be recombinant between TG389 and dgt (Figure 1).

  • For the binomial phenotype with a backcross design, sample size of 100, the 100 parameter combinations examined resulted in 34 showing no difference in statistical power between the intersection test and the two marker test ( i.e , the value of the difference was exactly zero), 39 favoring the intersection test, and 27 favoring the two marker test.

  • When both genetic variance and recombination load are considered together, a set of 100 RI strains should be approximately four times as effective (precise) for mapping complex traits as an F2, and eight times as effective as a backcross.
