If you cross homozygous recessive short plant with heterozygous purple

1.	If you cross homozygous recessive short plant with heterozygous purple flower to heterozygous tall plant with heterozygous purple flower, what will be the expected phenotypic ratio?(a) 9:3:3:1(b) 4:4:2:2(c) 3:1:3:1(d) 1:2:1:2:4:2:1:2:1I have been asked this question by my college professor while I was bunking the class.The above asked question is from Dihybrid Cross topic in chapter Mendelian Genetics of Cytogenetics
Answer» Correct answer is (c) 3:1:3:1 Explanation: In this cross the ratio WOULD be as follows 3(tall PURPLE): 1 (tall WHITE): 3 (short purple):1 (short white). This is a test cross for height GENE but not for colour gene.
