Question

gregor mendel crossed homozygous tall plants (tt) with homozygous short plants (tt). all the resulting offspri tall. from these results, what conclusion did mendel draw? tallness is a dominant trait. the word homozygous always means dominant. only dominant alleles are passed on to offspring. the alleles of the offspring were recessive.

Explanation:

Mendel's experiments showed that when a homozygous dominant (TT) and homozygous recessive (tt) are crossed, the offspring (Tt) show the dominant trait (tall). This is because the dominant allele (T) masks the recessive allele (t). The other options are incorrect: homozygous just means having two identical alleles (not always dominant), both dominant and recessive alleles can be passed (but dominant shows in this case), and the offspring's alleles were Tt (not all recessive).

Answer:

Tallness is a dominant trait.
