2) A tall plant (TT) is crossed with a tall plant (Tt).
3) A tall plant (Tt) is crossed with a short plant (tt).
4) A red flower (Rr) is crossed with a white flower (rr).
5) A white flower (rr) is crossed with a white flower (rr).
6. A homozygous dominant brown mouse is crossed with a heterozygous brown mouse (tan is the recessive color).
7. Two heterozygous white (brown fur is recessive) rabbits are crossed.
8. In some chickens, the gene for feather color is controlled by codiminance. The heterozygous phenotype is
known as erminette.
