If mendel had crossed a true breeding dominant plant with a true breeding recessive plant, in which of the three generations is the recessive trait visible?

If Mendel crossed a true breeding dominant plant with a true breeding recessive plant the recessive trait is visible in the F3 generation.

Explanation:

In Mendel’s cross the selected parents are a tall pea plant and a short pea plant. Tall is the dominant trait and short is the recessive trait.  Both the parents are homozygous.

Letter T represents tall and t represents short. Hence the phenotype TT is homozygous dominant and tt is homozygous recessive.  

The genotype Tt represents tall since T is dominant over t. Mendel’s cross can be represented as  

F1 generation      Tt     Tt   Tt   Tt

F2 generation     TT   Tt  Tt tt  

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )

what in the weirdo : o
