WebJun 16, 2024 · Dihybrid crosses come into play when there are two phenotypes involved. There is a reason though that breeders usually do not focus on only using one phenotype. If they do, they will never get to explore other possibilities and develop much more unique and promising features. WebMendelian Genetics Worksheet 2 • Dihybrid Cross Problems 1. In horses, the coat color black is dominant (B) over chestnut (b). The trotting gait is dominant (T) over the pacing gait (t).
