A AA Aa
a Aa aa

 

A = Yellow

a = green

Expected Phenotypic ratio 3:1

Yellow : green 

Phenotype Observed (O) Expected (E) O-E (O-E)2 Biology homework question answer, step 1, image 2
Yellow 4400 6024(.75) 4158 -118 13924 3.08
Green 1624 6024(.25) 1506 -118 13924 9.24
Totals 6024 6024     12.34

 

         

            n=2-1=1      P=3.84                 139244518=3.08      Hence, No data         139241506=9.24      does not fit predicted phenotype as           12:32>3.84.
