Final answer:
A 4:4:4:4 phenotypic ratio is a quadhybrid cross in genetics.
Step-by-step explanation:
A 4:4:4:4 phenotypic ratio is a quadhybrid cross. In genetics, a phenotypic ratio represents the ratio of different observable traits in the offspring resulting from a cross between individuals with different genotypes. A quadhybrid cross involves four different traits being inherited. Each trait follows independent assortment, meaning they segregate and assort independently during gamete formation.
