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