Question

Please answer these three questions completely (circle three choices for each question). Thank you!!

1. Let’s say that you have a homozygous deletion in gene Z in C. elegans. The animals are sterile. The gene is haplosufficient. What type of allele is this likely to be (Circle three)?
a. Loss-of-function
b. Gain-of-function
c. Recessive
d. Dominant
e. Amorphic
f. Hypomorphic
g. Hypermorphic
h. Antimorphic
i. Neomorphic

2. This question still relates to #1. Now let’s say you have a mutant allele (z3) in gene Z that leads to incompletely penetrant sterile phenotype as a homozygote. What type of allele is this likely to be (circle 3).
a. Loss-of-function
b. Gain-of-function
c. Recessive
d. Dominant
e. Amorphic
f. Hypomorphic
g. Hypermorphic
h. Antimorphic
i. Neomorphic


3. This question still relates to #1. Now let’s say you have a mutant allele (z3) in gene Z that leads to an incompletely penetrant sterile phenotype as a heterozygote in conjunction with the wildtype allele. What type of allele is this likely to be (circle 3).
a. Loss-of-function
b. Gain-of-function
c. Recessive
d. Dominant
e. Amorphic
f. Hypomorphic
g. Hypermorphic
h. Antimorphic
i. Neomorphic
