Parental Pheotypes
Long x ShortF1
All LongF2 Phenotypes
787 long, 277 short1. What is the expected value for the recessive phentotype of the cross Long versus Short
787+277= 1064
I did 787/1064= .739 Rounded up to .74 For Long
277/1064= .26 for Short
.74x1064= 787.36 Is the Expected value for Long. But this answer is somehow wrong in the system. I'm just trying to see if the system has an error because I don't see how it can be wrong. 2. What is the Chi Square Sum (rounding to 3 significant figures) for Long versus Short cross.
Long- (787-787.36)^2/787.36= 1.64E-4
Short- (277-276.64)^2/276.64= 4.68E-4
Add those number and I get 6.32E-4 which seems very wrong.
