Answer:

1:1.

Explanation:

Mendel is known as the father of the genetics. Mendels explained the concept of dominance - the trait that can express itself in heterozygous condition is known as dominant trait. The other trait that can not express itself is known as recessive trait.

The tall plants (T) is dominant and (t) is recessive. The cross between homozygous short plant (tt ) is crossed with heterozygous dominant (Tt).

Parents tt   ×   Tt.

offsprings: Tt ( tall) and tt ( short).

The expected genotypic ratio is 1 (tt) :1 (Tt).

Thus, the answer is 1:1.

What if plants AND humans needed photosynthesis to live?
hoa [83]

Answer:

Just 5% to 10% of the sunlight they receive gets converted into energy. So if humans are going to photosynthesize, we'd better get good at it. We would probably evolve to become a lot bigger to absorb enough light to feed and grow.

Hope this was helpful!❤
