Answer:
9:3:3:1
Explanation:
The ratio that result in dihybrid inheritance can be presented in the form of probability for two heterozygous traits in an organism. For example, during mendel's experiment using heterozygous tall pea plants and heterozygous purple flower,Both parents are heterozygous, and therefore one allele for each trait shows complete dominance. This simply indicates that both parents have recessive alleles, but express the dominant phenotype. The phenotype ratio predicted for dihybrid cross is 9:3:3:1( TT PP: Tt Pp: tt pp)
Nine combinations express offspring with both dominant phenotypes. Three combinations each producing offspring with one dominant and one recessive phenotype therefore the offsprings being heterozygous for the trait. One combination produces a complete recessive offspring.
