Question

tall pea plants are dominant over short pea plants. can a short pea plant ever be produced from crossing two tall pea plants? a. no, only short pea plants can produce short pea plants because it is a recessive trait b. no, short pea plants are a different type of pea plant and could never be the offspring of tall pea plants. c. yes, two heterozygous tall plants could produce short pea plants. d. yes, two homozygous tall pea plants could produce short pea plants.

Answer 1

C - two heterozygous tall plants can produce short plants. Each plant will have a recessive allele for shortness. If the parent plants each donate the recessive allele, the resulting plants would be short.
