You are tracking phenotypes in tulip plants (diploid). Gene T is involved in plant height, where 'T' is the dominant allele resulting in tall plants and 't' is the recessive allele resulting in short plants. Gene R is involved in petal color where 'R' is the dominant allele resulting in red petals and 'r' is the recessive allele resulting in yellow petals. Genes T and R are linked and both genes are haplosufficient. A cross is done between two dihybrid plants where one plant has the alleles linked in cis and the other plant has the alleles linked in trans. Assuming no recombination between genes T and R in either parent, what is the expected phenotype ratio for the F1 from this cross?
O 2 tall, red: 1 tall, yellow: 1 short, red
O 1 tall, yellow: 1 short, red
O 2 tall, red: 1 short, yellow
O 3 tall, red: 1 short, yellow
O 9 tall, red: 3 tall, yellow: 3 short, red: 1 short, yellow
