In dragons the gene F codes for fire colour. The Fallele produces red flames, which is dominant to the fallele that produces blue flames. On a different chromosome, a second gene T codes for spike length. The T allele is dominant to the t allele and results in long spikes. A male dragon who produces blue fire and is heterozygous for long spikes mates with a female dragon that has short spikes and is heterozygous for red fire production. What are the expected phenotypes and their ratios in their offspring from this cross?
a. Long spikes and red fire: long spikes and blue fire: short spikes and blue fire in a ratio of 1:2:1
b. Long spikes and red fire: long spikes and blue fire: short spikes with blue fire: short spikes with red fire in a ratio of 9:3:3:1
C. None of the other answers have the correct ratios
d. Long spikes and red fire: long spikes and blue fire: short spikes and red fire: short spikes and blue fire in a ratio of 1:1:1:1
e. Short spikes with red fire: long spikes with blue fire in a ratio of 2:1
