Question : What is monohybrid cross ? |
|
Answer» Solution :MONOHYBRID CROSS. It is a cross in which only one character is considered at a TIME, e.g., in a cross between tall and dwarf plant, the size of stem is considered. Mendel made a cross between pure tall (TT) and a pure dwarf (tt) PEA plant. He obtained all tall (hybrid) plants in `F_(1)` generation. On selfing these plants PRODUCED tall and dwarf in the ratio of `3:1` The genotypic ratio of `1:2:1` and phenotypic ratio of `3:1` is termed monohybrid ratio. |
