1. If there are n-gene pairs controlling a quantitative trait, then a parent that is an heterozygote (with one additive allele and one non-additive allele for each gene) will produce different kinds of gametes with respect to the number of additive alleles present: A. 2n (ranging from 0 to 2n additive alleles per gamete) B. 2n 1 (ranging from 0 to 2n 1 addtive alleles per gamete) C. n-1 (ranging from 1 to n-1 additive alleles per gamete) D. n (ranging from n 1 to 2n additive alleles per gamete) E. n 1 (ranging from 0 to n 1 additive alleles per gamete)
