This passage describes the growth pattern trait in rose plants: Climbing growth and bush growth are different growth patterns in rose plants. Rose plants with climbing growth have long, bendable stems that act like vines. These plants may grow upward to cover fences or walls. Rose plants with bush growth stay near the ground. These plants form low bushes or shrubs. In a group of rose plants, some individuals have climbing growth and others have bush growth. In this group, the gene for the growth pattern trait has two alleles. The allele G is for climbing growth, and the allele g is for bush growth. A certain rose plant is from this group. This rose plant's phenotype for the growth pattern trait is climbing growth. This plant's genotype for the growth pattern gene is GG. Based on this information, complete the following statement. This rose plant is heterozygous or homozygous for the growth pattern gene.
