An allele masked or hidden by the presence of another is referred to as: - recessive When two individuals who are heterozygous for a trait mate, what is the probability that their offspring will exhibit the dominant trait? - 75% For the results of Mendel's dihybrid cross to be a 9:3:3:1 ratio of traits, what must the relationship of each gene pair be? - The genes must be on separate chromosomes. When Mendel crossed two "true-breeding" pea plants with contrasting traits (e.g., tall versus...
