The f2 generation phenotypes resulting from the monohybrid cross of purebreds display a ratio of 4: 1 2: 1 3: 1 none of the above

The correct answer would be 3:1

Let us take an example of TT and tt as purebreds.

T is a dominant trait which codes for tallness and t is a recessive trait which codes for a dwarf trait.

The F₁ generation would be Tt, that is, heterozygous dominant.

The F₂ generation would produce offspring with three possible types of genotypes TT, Tt, and tt in ratio 1:2:1.

Thus, the phenotype ratio would be 3 (tall): 1 (dwarf).

primary succession occurs in essentially lifeless areas regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier. secondary succession occurs
