explain in details mendle experiment for single trait TT and tt in plants
Answers
Answer:
Hey mate....
In Mendel's experiment, the parent plants were homozygous (eg, T T or t t ) for the measured trait, because they could produce only plants with that trait, if they were self-pollinated. That is, they bred true.For example, parent plants produced only smooth (S) or wrinkled (s) seeds when self-pollinated.
Hope you understand!!!
Explanation:
mendal took two pure plants and cross pollinated them. one of the plants was tall (TT) while other was dwarf (tt) .
in first (F1) generation,he obtained all tall plants. In F1 generation,there was neither dwarf plant not any plant of intermediate height. this meant that only one of the parental traits was seen. Mendal then carried out the selfing of F1 plants ( i.e selecting nale and female plants from the same generation and usingthem as parents for developing next generation F2) . On selfing of F1 plants Mendal obtained a ratio of 3 ratio 1 between tall and dwarf plants in F2 generation
