Genes A and B are located 10cM from each other on a chromosome. Gene C is located 25cM from gene A and 15cM from gene B. Assuming that I = 0, what is the probability that the trihybrid ABC/abc will produce an ABC gamete?

I get that ABC is a result of a double crossover. A similar question was answered and said that

Probability of SCO - DCO = 0.25 - 0.015 = 0.235

PLEASE EXPLAIN HOW YOU GET .25 and .015. Please do not say that it's SCO and DCO actually please explain Did they get that SCO is .25 because that's A to C, and did they say .015 because that's distance from C to B and B to A? Please I am very confused. Thanks.

You have three genes on the same chromosome - A, B and C. Each gene has two alleles in a dominant/recessive relationship. For these genes the homozygous recessive has the mutant phenotype for that trait, the dominant phenotype = wild type for that trait. allele A is dominant to a; phenotype a = mutant for trait a; phenotype A = wild type for trait A allele B is dominant to b; phenotype b = mutant for trait b; phenotype B...
