By crossing homozygous short purple flowering parent with a heterozygous tall purple flowering parent you get 41 tall progeny. What will be the expected number of short progenies?
A. 12
B. 42
C. 60
D. 80
I have been asked this question by my school principal while I was bunking the class.
This interesting question is from Dihybrid Cross in portion Mendelian Genetics of Cytogenetics
The correct option is B. 42
To elaborate: This is a case of a test cross for the Height allele. The ratio should be 1:1 for short: tall. If there are 41 tall progeny there must be a similar number say 42 of short ones.
