In garden peas, tall (T) vine is dominant over short (t) vine, and round pea pod (R) is dominant over wrinkled pea pod (r). Cross a heterozygous tall wrinkled pea plant with a short heterozygous round pea plant.

Answer:
Explanation:
Given:
Traits
T (tall, dominant) and t (short)
R (round, dominant) and r (wrinkle)
Crossing parents
hetero-zygous. tall wrinkled (Ttrr)
phenotype tall is given hetero-zygous., so Tt
phenotype wrinkled is recessive, so must be homo-zygous rr
Foiled genotypes (Tr, tr, each with 50%)
short hetero-zygous. round (ttRr)
phenotype short is recessive, so homo-zygous rr
phenotype round is given heteroz. so Rr
Foiled genotypes (tR, tr, each with 50%)
