In any dihybrid cross where both parents are heterozygous for both traits, what is the phenotypic ratio of the offspring?

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.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
