During Mendel's pea experiment Mendel crossed a ______ tall pea plant with a _____ short pea plant (the p generation).
During Mendel's pea experiment Mendel crossed a ______ tall pea plant with a _____ short pea plant (the p generation).

In Mendel's experiments, during the F1 generation why were all of the pea plants tall?
In Mendel's experiments, during the F1 generation why were all of the pea plants tall?
Cross TT with tt will result in all offspring being hybrids, Tt, which means they will be have the dominant phenotype, but can still carry the recessive allele.
