Question

how do you solve this?

You isolate 8 independent mutant worms with abnormal color. (normal/wild type color = + and mutant/abnormal color =-). Based on the outcomes from crosses between the mutants isolated you generate the table below. + + + + N + + 1 a. Fill in the + or - sign in boxes 1, 2 and 3 in the table above. b. What are the complementation groups based on the crosses outcomes shown in the table above? c. How many genes did you identified to affect color in these worms? d. How many different alleles did you identified in total?

Answer 1

Please find the answers below

	A	B	C	D	E	F	G	H
A	-	-	+	+	-	+	+	-
B		-	+	+	-	+	+	-
C			-	-	+	+	+	+
D				-	+	+	+	+
E					-	+	+	-
F						-	-	+
G							-	+
H								-

A. Fill in ‘+’ or ‘-‘ sign in boxes 1, 2 and 3 in the table above

B. What are the complementation groups based on the crosses outcome shown in the table

Answer: Complementation explains whether the gene is present on same or different chromosome

A,B,E,H are mutations in one gene

C,D are mutations in one gene

F and G are mutations in one gene

So there are three(3) complementation groups

c. How may genes did you identified to affect color in these worms

Answer: Atleast three genes affect colour in these worms

d. How many different alleles you identified in total

Answer: 3 alleles

Alleles are two or more alternate forms of a gene and are found at the same place of chromosome
