The locus T (2 alleles, T1= tall plants and G2=short plants) in moss controls plant height in the gametophyte (haploid stage) but has no effect on phenotype in the sporophyte (diploid) stage. Sperm from a tall moss gametophyte fertilizes an egg from a short moss gametophyte to produce a sporophyte. This sporophyte produces spores, which grow up to be new gametophytes. What will be the heights of the next generation of gametophytes?
a) all intermediate in height
b) all short
c) all tall
d) half short and half tall
e) no way to tell from the information given
