Answer 2

Heya!!

_____________________✨✨✨

1) Phenotype simply means external or morphological expression.

TT × tt

→Tt Tt Tt Tt

all progeny were tall... explained by Mendal in his law of dominance.

2)F2 phenotypic ratio is 9:3:3:1

3)In F2 generation phenotypic characters of parents (F1 generation) appears due to the segregation of homologous chromosomes.

explained by Mendal in law of independent assortment.
