Consider a trait caused by two loci - the color1 locus and the color2 locus. At the color1 locus there are two alleles (C1 and c1). At the color2 locus there are also two alleles (C2 and c2). At the color1 locus, each allele affects the phenotype as follows - C1: +0.15, c1 = -0.01. At the color2 locus, each allele affects the phenotype as follows - C2: +0.25, c2 = -0.10. What is the additive genetic effect of the following genotype C1c1C2C2 (give your answer to two decimal places)?
