Show a Mendelian experiment where tall pea plants are crossed with dwarf plants Write both the phenotypic and genotypic ratio for F, generation.
Answers
Answer:
hen Mendel crossed a true breeding tall plant (female parent) with a true breeding plant of the dwarf variety (male parent), he got tall plants like one parent in the first filial generation designated F1. He used the term “dominant” for the tall character which dominated in the F1. generation, and “recessive” for the character of dwarfness which remained hidden (latent) in the F generation. All plants are tall in F1.
b) Self-fertilization of the F1 hybrids produced the second filial generation F2 consisting of a total of 1064 plants of which 787 were tall and 277 were dwarf. That is tall and dwarf plants appeared in F2 in the proportion of 2.84:1 which is roughly equal to 3:1. The percentage of dwarf plants is 25%.
c) In F1 generation TT X Tt will give offspring 50% TT and 50 % Tt. In F2 generation when They are again self-crossed, the gamets will be T from TT and Explanation:
