Answer:
Referring to the attached figure, there are two alleles V and v for height. The reason for using capital and small letters is to indicate the dominant or recessive nature of the allele.
<u>Explanation:</u>
Dominant (V):
An allele that is dominant means only one copy of that allele is enough for the expression of trait. For example, if V is for tall height, an individual with genotype Vv or VV both will have tall height because they have the allele of tall height that is dominant in nature.
Recessie(v):
An allele that is recessive nature means two copies of that allele are mandatory for the expression of trait. For example, if v is for short height, an individual with genotype vv will have short height because they have two copies of same alleles that are recessive in nature. However if the genotype is Vv, still the individual will have tall height because capital letter is masking the effect of small letter (v allele). This is because of recessive nature of allele.

Mutation rate of Gram negative bacteria is much greater than that of Gram positive bacteria.
Explanation:
The gram positive types of bacteria responsible for causing diseases in humans. It is called as Gram positive bacteria. Both the bacteria are different in structural and physical properties. It is defined as the group of bacteria’s which positive result in gram stain test.
Gram negative bacteria are the group of bacteria’s which gives negative result to the gram stain test. This classification is done according to the cell wall. The cause of common disease by Gram positive bacteria is our anthrax, diphtheria, etc.
Pain that may be perceived at a distinct point on the surface of body ,such as the back or shoulder is called as referred pain .
what is referred pain ?
Referred pain is also known as reflective pain ,which is perceived at a location other than the site of the painful stimulus .
Example is case of angina pectoris brought on by heart attack where the pain is often felt in left side of neck ,left side of shoulder and back rather than in the thorax ( chest ) which is the site of injury.
Referred pain often experienced n the same side of the body as the source ,but not always .
Hence the correct answer is Referred pain .
