PLEASE explain how to do this question step by tspe i am very confused! thank you!

You have three independent mutant alleles in the Drosophila gene no legs (nlg): nlg¹, nlg², and nlg³. You assay the phenotype of Drosophila, which is an insect, that are heterozygous for the three allele (heterozygous for a wild-type and a mutant allele), and that are homozygous for the three alleles.

Allele	nlg¹	nlg²	nlg³
heterozygous	Wild-type	Four pairs of legs	Wild-type
homozygous	Stumpy legs	Five pairs of legs	No legs

nlg¹ is a ___X___ allele, nlg² is a ___Y___ allele, and nlg³ is a ___Z___ allele.

	X	Y	Z
A	Gain of function	Null	Hypomorphic
B	Hypomorphic	Gain of function	Null
C	Null	Gain of function	Hypomorphic
D	Null	Hypomorphic	Gain of function
E	Hypomorphic	Null	Gain of function

Referencing the table above, select the correct answer:

1 : A

2 : B

3 : C

4 : D

5 : E

Correct answer is B
