Question

Please explain how you do this question step by step I am very confused! thank you:)

You have three independent mutant alleles in the Drosophila gene no-antenna: nan1, nan2 and nan3. You determine the phenotype of Drosophila that are heterozygous for the three alleles (heterozygous for a wild-type allele and a mutant allele), and that are homozygous for the three mutant alleles. The antenna is composed of three segments that are followed at the distal end by a feathery arista (that is the antenna is composed of three segments and an arista).

Allele	nan¹	nan²	nan³
heterozygous	Wild-type	No arista	Wild-type
homozygous	No arista	No antenna	No antenna

nan¹ is a __x__ allele, nan² is a __y__ allele, and nan³ is a __z__ allele.

	X	Y	Z
A	Dominant negative	Null	Hypomorphic
B	Null	Dominant negative	Hypomorphic
C	Null	Hypomorphic	Dominant negative
D	Hypomorphic	Dominant negative	Null
E	Dominant negative	Hypomorphic	Null

Referencing the table above, select the correct answer:

1 : A

2 : B

3 : C

4 : D

5 : E

The correct answer is: D. just please explain the steps!!
