Answer 1

Answer:

Phenotype	Observed(O)	Expected (E)	O-E	(O-E)2	(O-E)2/E
red, long	123	105	18	324.00	3.09
white, short	137	105	32	1024.00	9.75
white, long	74	105	-31	961.00	9.15
red, short	86	105	-19	361.00	3.44
Total	420	420			25.43

Chi-square value = 25.43

Degrees of freedom = number of catergories -1 = 4 – 1 = 3

Probability value at 0.05 or 5% = 7.81

The chi-square value of 25.43 is greater than the critical value of 7.81. We can reject null hypothesis. Hence the two traits are linked and the ratio, 1:1:1:1 as expected is not possible.
