Mendel made crosses between pure-breeding short pea plants with purple flowers and pure-breeding tall pea plants with white flowers. The alleles for a tall height and purple flowers were dominant. This cross is written as _____.

A. TTPP × ttpp
B. TtPp × TtPp
C. Ttpp × ttPp
D. ttPP × TTpp

Answer 2

D is the correct answer because the capital letter represents the dominant allele. All of the plants are pure bred. The first pea plant is short (tt) with purple flowers (PP). The second is tall (TT) with white flowers (pp). Therefore the cross is ttPP x TTpp
