Question

I’m not sure how to complete the zero observed and mode of inheritance

Mutant o Mutant o #WT - 1子 Males : , Mutation D Possible Mode | (0-E)2 Reject or Fail to # Observed 3(rec):1(dom) or | # Expected (E) | (0-E) Female Male) Mutant (Female+ o Total Flies Hypothesis 丨 (Reject or Fail to Reject) Possible Mode of inheritance # Observed | Expected Ratio | # Expected (E) | (OE) If Sex-Linked 32 44 WT Females G.25 12 4.25-4285. 4.25 Total Flies 32.44

Answer 1

F2 - GENERATION DATA
MUTATION D	#WT FEMALES =  20		# MUTANT FEMALES= 0		#WT MALES =  17		# MUTANT MALES= 0
IF AUTOSOMAL	# OBSERVED (O)	EXPECTED RATIO 3:1	#EXPECTED (E)	(O-E)	(O-E)^2	(O-E)^2/ E	X^2	HYPOTHESIS (REJECT OR FAIL TO REJECT)	POSSIBLE MODE OF INHERITANCE
WT (F+M)	37	75%	27.75	9.25	85.5625	3.083333333	12.33333333	DF = 1
MUT (F+M)	0	25%	9.25	-9.25	85.5625	9.25		FAIL TO REJECT	AUTOSOMAL P=1
TOTAL	37
IF SEX LINKED	# OBSERVED (O)	EXPECTED RATIO 1:1:1:1	#EXPECTED (E)	(O-E)	(O-E)^2	(O-E)^2/ E	X^2	HYPOTHESIS (REJECT OR FAIL TO REJECT)	POSSIBLE MODE OF INHERITANCE
#WT F	20	25%	9.25	10.75	115.5625	12.49324324	37.48648649	DF = 3
#MUT F	0	25%	9.25	-9.25	85.5625	9.25		FAIL TO REJECT	P= 2
