Generating an allelic series of paintball mutants | Quick Homework Help

Red pigment is produced in a fictional plant through the action of the gene paintball (P). Flowers of varying intensity from pale pink to bright red are made when the activity of the paintball enzyme is between 24 and 50. When the level of enzyme is below 24 the flowers fail to develop. When the level of enzyme activity exceeds 50, the flowers explode and spray red pigment on unsuspecting bystanders (hence the name of the gene). You decide to generate an allelic series of paintball mutants with the following activities.

This locus is …

A) Haploinsufficient
B) Gain of function

C) Hemizygous
D) Dominant
E) Recessive
F) Loss of function                            

P1 is ____________ to wild type.

A) Dominant
B) Recessive
                                                     P2 is ______________ to wild type.A) Dominant
B) Recessive                         

Should you wear a white shirt to work if you are looking at the progeny of a cross between two flowers with the genotype P¹P³?

A) I’m not going to work today, there won’t be any flowers to look at because they have inadequate paintball activity.
B) I think I’ll wear my lab coat and goggles since there is a 25% chance that any given flower will explode.
C) I think I’ll wear my lab coat and goggles since there is a 75% chance that any given flower will explode.
D) I think I’ll wear my lab coat since there is a 50% chance that any given flower will explode.
E) Sure, none of the flowers will explode.
Allele 4 is a dominant negative mutation that interferes with normal protein function generating a phenotype when heterozygous with wild type. Is this mutation dominant to allele 3?A) Yes B) No
