Question

The F1 progeny of mendel experiment is represented as Th , the plant is phenotypically tall state why it is not TT?

Answer 1

Answer:

If I am not wrong then we take TT and tt for first cross

t. t

T| Tt. Tt

T| Tt. Tt

all the progeny in F1 generation are heterozygous tall

Now ,your question was why is Tt considered tall

So ,according to ncert T is dominant and will show its character even in the presence of t(small t) . however t(small t) is recessive and will only show its characteristic when in tt(2 t are present together)

Therefore Tt is a tall plant as only T(capital T ) is showing its characteristic suppressing the character of t(small t).
