Answer and Explanation:
The Huntington disease is caused by a mutation in the gene that codifies for the Huntingtin protein (Htt). The mutation produces an altered form of the protein leading to the neuron´s death in certain areas of the brain.
The Huntington disease characterizes for being,
- Hereditary, passing from generation to generation. To express the disease, a person must have been born with an altered gene.
- Autosomal, affecting men and women equally, because the mutated gene is located on an autosomal chromosome.
- Dominant, which means that by getting only one copy of the altered gene coming from any of the parents, the receiving person will express the disease. The mutation in the gene dominates over the normal gene copy.
- Expressed by heterozygosis. Most people affected by the disease are heterozygous, with a normal copy and a mutated copy.
There are just a few cases all around the world (3% approximately) in which the disease is expressed with no family history. The progenitors are not affected by the mutation. These cases are very rare and are called <u>"de-novo" mutations.</u> A new mutation is spontaneously produced and it is not inherited from any of the parentals. It consists of an increase in the number of CAG repetitions. In a normal person, the number of CAG repetitions is less than 35. When there are 40 or more repetitions it occurs the disease. But when there are between 35 and 39 repetitions, the penetrance of the disease is incomplete. This is a "gray zone". Those alleles that fall in the gray zone are unstable and might produce the HD. Individuals with these unstable alleles have a tendency to increase the number of repetitions from generation to generation until the number reaches 40 repetitions and the person expresses the disease. This <u>usually occurs in the paternal germinal line</u>, as it is particularly unstable in sperm and probably meiosis greatly affects their instability, causing an increase in the number of CAG repeats.
Crop monitoring makes use of space-based data to keep tabs on crop development and forecast crop yields for certain fields that have been planted.
<h3>What is monitoring systems?</h3>
A system for monitoring agriculture consists of a network with wireless sensors. These sensors gather information from several nodes positioned on the playing surface. Then, specialists or nearby farmers analyze this data. The data can be used to make a number of inferences about weather patterns, soil fertility, crop quality, etc. A system is developed for agricultural field monitoring in IoT-based modern agriculture with the aid of sensor like light, humid, temperatures, soil moisture, etc. Farmers may monitor the condition of thier fields from any location. IoT-based smart farming is considerably more efficient than conventional farming.
<h3>How do farmers monitor their crops?</h3>
Nowadays, satellite techniques are widely employed in agriculture, and many farmers use them frequently to observe their fields and assess the condition of their crops. Crop monitoring is crucial for managing various pests, weeds, and diseases that affect crops. This gives information about the crop's current situation, and you can then look ahead in time to forecast what will probably be the crop's next problem.
