A) What do we call the type of allele that is usually produced by a loss of function mutation? ____________________________________________________
B) Alleles created by gain of function mutations often behave in what manner when they are present with a wild type allele? ______________________________ please explain
Homework Answers
Answer. An allele that is usually produced by a loss of mutation is called as "non functional allele" because if a function is lost by mutation then the protein produce is not functional and call non functional.
Alleles created by gain of function mutations often behave as dominant allele or semidominant because they have gain of function that might be dominant over wild type allele or semi dominant

A mutated allele is a variant of the original “wild type” allele. A mutated allele can mutate again. The first mutation discovered receives the primary code for that locus, for example, 1xxxxx. How do we code for other mutations at the same gene locus when they are found? Please give an example.

In a case where we see a class of loss-of-function mutations and null alleles being produced. Can we assume its due to a mutant site on the promoter. Or a mutant site on an exon? As well for null alleles would transcript be detected on these sites and would we see a polypeptide form?

In Drosophila (fruit flies) the genes how, dumpy and ebony are located on chromosome 3. LOF = loss of function. Flies homozygous for a LOF mutation (no gene product made) in ebony have dark black bodies. Flies homozygous for a LOF mutation (no gene product made) in dumpyhave truncated (short) wings. Flies homozygous for a partial LOF mutation (some gene product made but significantly less than normal) in how have wings that will not fold down (held out wings; that's...

Please help answer
Conditional alleles are mutant gene versions encoding proteins that can function normally at the permissive condition but are defective at the restrictive condition. One commonly used condition is temperature. Conditional alleles are especially useful to geneticists because they permit the study of essential genes. At the permissive temperature, the organism lives normally. When the organism is shifted to the non-permissive temperature, the effect of inactivating the gene can be studied. Which of the alleles shown below (mutations...

Explain what classifies a mutation as “temperature‑sensitive” by comparing phenotype(s) with a wildtype allele. How is this type of phenotype explained by protein behaviour? Would the following types of mutations most likely have: severe effects, mild effects, or no effect on protein function? Briefly explain your answers. Note that there may be more than one correct answer, but you need only to give one sensible answer and explain your reasoning. [6 marks] A nonsense mutation occurring in sequences encoding amino...
