1. Assume you are trying to create a rose bush that has deep red roses and small thorns. Rose color is determined through the R gene. Thorn size is determined by the T gene. The red rose phenotype is a dominant trait and white roses are the recessive trait for flower color while the small thorn phenotype is a recessive trait and large thorns are the dominant trait.

a. If you crossed a thorn bush that was heterozygous for flower color and thorn size with a thorn bush that had white flowers and was heterozygous for thorn size, what would be the phenotypes of the offspring and the phenotypic ratios?

b. If you observed 100 rose bush offspring, how many would have the desired phenotype?
