Answer: A. Genotype: 1/2 Yy; 1/2 yy. Phenotype: 1/2 Yellow; 1/2 Green.

Explanation: The answer lies in Punnett´s Square. A visual representation of Mendelian inheritance. Dominant genes always express when an organism presents them. Recessive genes express when both alleles contain the recessive gene. A heterozygote contains different alleles for the same gene (Yy). A homozygote contains the same alleles for the same gene (YY/yy), which can be a Dominant (YY) or Recessive (yy) Homozygote.
