Which of the following is a totally impossible outcome of Mendel’s Experiment?3 tall 1 short24 tall 8 short8 tall 0 short4 tall 1 medium height

The totally impossible outcome of Mendel’s Experiment from the given options is "4 tall 1 medium height".

Mendel's experiments were based on traits that were controlled by a single gene with two alleles, one of which could be dominant over the other. In this case, height in pea plants is controlled by a single gene with two alleles: one for tall plants (dominant) and one for short plants (recessive).

There is no "medium height" category in Mendel's experiments. The plants were either tall or short, based on whether they had the dominant or recessive allele. Therefore, the option "4 tall 1 medium height" is not a possible outcome of Mendel's experiments.
