What is the difference between genotype and phenotype
dlinn [17]

Answer:

  • person’s <u>genotype</u> is their unique sequence of DNA. More specifically, this term is used to refer to the two alleles a person has inherited for a particular gene. <u>Phenotype</u> is the detectable expression of this genotype – a patient’s clinical presentation.

Explanation:

person’s phenotype results from the interaction between their genotype and their environment.

The connection between genotype and phenotype is not always clear-cut. This means that you may encounter disparities between your patient’s genomic test result and their clinical presentation. Similarly, the phenotype of patients with a given genetic condition may vary greatly even within families.

From the following, choose the factors that may produce or increase the risk of mutations.
mel-nik [20]

Answer:

High Temperature, X-rays, Radiation, Some Chemicals

Explanation:

In general, mutations happen due to some error in the DNA duplication process, however, there are certain factors in the environment that can increase the incidence rate of these genetic errors. Excessive exposure to x-rays, substances present in smoke, ultraviolet light, excessive temperature, nitrous acid and some dyes present in food, for example, can favor the appearance of mutations. In general, we can say that mutations can be caused by high temperature, X-rays, radiation, some chemicals.

Describe and explain the changes in electrical activity both in receptor and in the sensory neurone as increasing pressure is ap
blsea [12.9K]
<span>Pacinian corpuscles are rapidly adapting mechanoreceptors so they respond only at the onset and offset of the stimulus. The Pacinian corpuscle has a single afferent nerve fiber. Its end is covered by a sensitive receptor membrane whose sodium channels will open when the membrane is deformed in any way. Pressure thus causes sodium to enter the neuron and create a generator potential. If this potential reaches a certain threshold nerve impulses are formed. This impulse is now transferred along the axon with the use of sodium channels and sodium/potassium pumps in the axon membrane. The magnitude of the stimulus is encoded in the frequency of impulses generated in the neuron. So the more massive or rapid the deformation of a single corpuscle, the higher the frequency of nerve impulses generated in its neuron.</span>
