Additive genetic variation is found when: more than a single locus is involved in determining a trait's value dominance and epistasis are absent from the genotype phenotype map the allelic effects are summed across loci to determine a trait's value a trait's value is heritable more than one hundred loci are involved in determining a trait's value

Step 1
Option A states that more than two single locus is involved in determining a trait's value, which is correct as additive genetic variation involves multiple genes. Option B states that dominance and epistasis are absent from the genotype-phenotype Show more…

The cross AB/ab x ab/ab produces the following progeny: AB/ab 404 ab/ab 396 aB/ab 97 Ab/ab 103. From these data, one can conclude that the recombination frequency between the A and B loci is %. Formulas: % of recombination = (number of recombinant progeny / total number of progeny) * 100 A. 20 B. 5 C. 15 D. 10 E. 25
