How can an organism have altered phenotype without ant mutation?

Expert Solution

Answer:-

Without any mutation the phenotype can only be changed due to environmental conditions.
Environmental conditions can alter the phenotype of an individual. If an individual is kept in a condition for long term, the individual will adopt the condition and it will show its phenotypes according to the condition.
It will not show its phenotype according to its birth place.

E.g : ALASKAN MALAMUTE is a dog of cold region. It has long hair. This long hair is its phenotype. If this dog is kept in warm region like India or Bangladesh from birth with some careful observation it will survive, but the long hair will be less long or less in number. This long hair is for protecting the body from cold, but in warm region it is not needed. Here environmental conditions changed the phenotype.
That's how environmental conditions can alter phenotype.

a) (i) What is it about a mutant phenotype that classifies the mutation as “temperature-sensitive”? (ii) How is this type of phenotype explained by protein behaviour? b) 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. (i) A nonsense mutation occurring in...

A mutation replaces the original amino acid, leucine, with threonine in a large protein. The altered protein still functions, but less efficiently. What amino acid might replace leucine but with less effect on protein functions? What amino acid might replace leucine but with even a worse effect on the how the protein functions? a) less effect if lysine; worse if alanine b) less effect if methionine; worse if lysine c) less effect if methionine; worse if alanine d) less effect...

You discover an organism with a new mutation in the gene that you are studying that changes the codon in the mRNA from a GCC (Ala) to a GAC (Asp) causing a mutant phenotype. You feed this organism a mutagen and find that in one of its progeny the phenotype has now reverted back to wild-type. When you look at your gene in this offspring you find the mutation GAC (Asp) has been changed back to the original GCC (Ala)....
