T=Tall, t=short & B=Black fur, b=white fur. Cross One-fourth of the F2 generation would be homozygous dominant (GG), one-half would be heterozygous (Gg), and one-fourth would be homozygous recessive (gg). A monohybrid cross also signifies a genetic mix between the two individuals having heterozygous genotypes. Each parent is chosen to be homozygous or true breeding for a certain trait to carry out such a cross (locus). golden bee broadmoor menu. However, each parent possesses different alleles for that particular trait.
