Keeping in view Mendel's law of Segregation, if tall plants were crossed with short heighted plants, then which of the following best describes the F1 Progeny?

Explanation

Mendel's law of segregation states that alleles separate during gamete formation, and each gamete carries only one allele for each trait. In this case, when a homozygous tall plant (TT) is crossed with a homozygous short plant (tt), all F1 offspring are heterozygous (Tt). Since the tall allele (T) is dominant over the short allele (t), all F1 plants appear tall. Option B is correct because the F1 generation is heterozygous (Tt) and exhibits the tall phenotype. Options A and C are incorrect because they describe homozygosity, which is not the case for the F1 generation. Option D is incorrect because it describes a heterozygous short phenotype, which is impossible due to the dominance of the tall allele.
