The probability that the child will not inherit Huntington’s disease is therefore 1/4.
<h3>What is Probability?</h3>
This is defined as a numerical description of how an event is likely to occur and the formula is :
Number of favourable outcomes/Total Number of outcomes.
When the heterozygous traits(Hh × Hh) are crossed, we have HH, Hh, Hh, hh.
The recessive trait is hh which makes the probability to be 1/4 in which the resulting child will not inherit the disease.

Answer:
Noncoding DNA does not provide instructions for making proteins. ... Such elements provide sites for specialized proteins (called transcription factors) to attach (bind) and either activate or repress the process by which the information from genes is turned into proteins (transcription).
Explanation:
Genotypes are the genetic composition of the organism. The alleles for the genotype are located at the genetic loci of the chromosome inherited from each parent.
<h3>What are alleles and genetic loci?</h3>
The alternate version of the genes that code for the hereditary trait and characteristic of the organism giving them the genotype and the phenotype is the alleles.
Genetic loci is the designated position found on the chromosome of the organism possessing the alleles coding for the genotype that can be purebred dominant and recessive, and heterozygous.
Therefore, alleles are physically present on the loci.

Answer: Both require A) Acceptance from the scientific community. B) Extensive amounts of valid evidence supporting the law and theory.
Explanation:
Answer:
<u>The disadvantages of 'bio-magnification are:</u>
<u>Impact on Human Health</u>
Biomagnification makes humans more prone to cancer, kidney problems, liver failure, birth defects, respiratory disorders, and heart diseases.
<u>Effects on Reproduction and Development of Marine Creatures</u>
The toxic chemicals accumulate in the important organs of aquatic organisms that affect their reproduction and development processes.
For eg., the shells of the eggs of the sea-birds are very thin that might get crushed by the birds themselves during incubation. The toxic chemicals, mercury and selenium destroy the reproductive organs of aquatic creatures.
<u>Destruction of Coral Reefs</u>
Cyanide that is used in leaching gold and fishing is the main cause of the destruction of coral reefs. Coral reefs are the dwelling and feeding grounds for many sea creatures. Their destruction affects the lives of many aquatic animals.
<u>Disruption of Food Chain</u>
The chemicals and toxins which are released into the water bodies disrupt the food chain. The small organisms absorb the toxins which are eaten up by larger animals. These toxins, thus, get accumulated in the higher level of organisms.
