Question

In a pea plant that breeds true for tall, what possible gametes will be produced

Answer 1

There are two possibilities, i.e. it can be either homozygous tall (TT) or heterozygous tall (Tt). In a test cross, tall pea plant of unknown genotype is crossed with dwarf pea plant. Dwarf plant is always homozygous (tt) as tallness is dominant allele and the dwarfness is recessive allele in pea.17
