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).

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

several tissues working together form an organ, and several organs together make up an organisms.

the group of cell that carries out special jobs are tissue.
