реа
(i) What is the phenotype and genotype of the Fı generation if a homozygous
tall plant is crossed with a homozygous dwarf plant?
(ii) Draw a Punnett square board to show the gametes and offspring when both
the parents are heterozygous for tallness.
(iii) What is the phenotypic ratio and genotypic ratio of the above cross in (11)?
(iv) State Mendel's Law of Dominance.
(v) What is a Dihybrid Cross?​

Answer 1
