1. C) Both parents contributed a recessive allele
The offspring is homozygous for the recessive allele, which means it has two copies of it. Because each parent contributes one copy of the gene, this means that both parents contributed the recessive allele.
2. D) The offspring can be tall or short
The first cross between TT and tt will yield an F1 generation with the genotype Tt. When this generation is self-pollinated, the cross may result in the following genotypes:
TT, Tt, tt
Which means that the offspring can be tall or short.
