The pedigree below depicts a dominant trait. What is the genotype of individual I-1 (use the letter A for a dominant allele and a for a recessive allele)? How did you come to this conclusion? Using your best grammar, write 3-5 sentences.

Answers

A pedigree chart is a diagrammatic representation showing the occurrence and appearance of phenotypes of a particular gene/traits and its ancestors from one generation to the next establishing relationships between individuals in a family.

Using the letter A for a dominant allele and a for a recessive allele, the genotype of individual I-1 is Aa.

In the key pedigree nomenclature, an individual marked with the black ink is affected with the trait (and this trait is dominant - A). Looking at the F1 generation, there are males affected and females as well. For inheritance of the trait, just one copy is enough to become affected. Therefore, the male parent is heterozygous for the trait and the female normal (aa) to enable the production of both affected and non-affected individuals.

Tortoise shell cats, like the one shown above, are always femaleWhat scientific phenomenon explains the color pattern of

Answers

Tortoise shell cats can be explained as the offspring from a incomplete dominance cross. Incomplete dominance gives rise to an intermediate phenotype.

The scientific phenomenon that explains the color pattern is X-linked incomplete dominance.

As stated earlier, the tortoise shell colour is as a result of incomplete dominance but as it exists only in females, the inheritance is X linked. This means the tortoise shell colour is inherited in the heterozygous condition as females have two X (XX) and males (XY) can only be either of the parent's true breeding genotype.

Answers

the most abundant is cells

The most abundant in the body is cells.

What do you mean by cells?

Cell is the smallest unit that can live on its own and that makes up all living organisms and the tissues of the body. A cell has three main parts: the cell membrane, the nucleus, and the cytoplasm.

Moreover, they provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body's hereditary material and can make copies of themselves. Cells have many parts, each with a different function.

There are two main types of cells: prokaryotic cells and eukaryotic cells. Prokaryotic cells include bacteria and archaea. Prokaryotes—organisms composed of a prokaryotic cell—are always single-celled (unicellular). Prokaryotic cells don't contain a nucleus.

Which is a point mutation and not a frameshift mutation?
mutagen
insertion
deletion
silent

Answers

Answer:

The correct answer is D. Silent

I can assure this is the correct answer because I took either the test or review, I don't remember but yeah I know its correct also, because of the other person so be sure to say thanks to them before me!

Hope I helped! <3

A silent mutation is a point mutation and not a frameshift mutation. Therefore, the correct statement is option D.

What are point mutations?

Mutagens are agents causing mutations in DNA sequence. Point mutations are due to a change in a single nucleotide base in a DNA sequence and frameshift mutations are due to changes that are the result of the insertion or deletion of nucleotide bases, thereby, shifting the reading frame of the sequence and the way is changed in which it is translated into a protein.

A silent mutation is a point mutation that does not change the amino acid sequence of a protein, as the mutated codon still codes for the same amino acid, thereby, not affecting the function of the protein.

Insertion and deletion mutations are frameshift mutations as they alter the reading frame of the sequence which results in a completely different amino acid sequence.

Therefore, the silent mutation is a point mutation.

The Statue ofLiberty stands on Liberty Island, near Manhattan in New York. Though she is often thought to beresident of New York, Liberty Island is actually federal property, which means that the Statue ofLiberty belongs to the whole country. The Statue of Liberty is not only the tallest statue in America, itis also one of the most recognizable American symbols.The Statue of Liberty is huge. From the tip of the torch to the pedestal which is the base of the statueon which she stands, she is just over 151 feet tall. If you include the pedestal in your measurement,she stands more than 305 feet off of the ground. Thats more than 30 basketball hoops or an entirefootball field. Her waist size is 35 feet, which would make it awfully tough to find pants, and thetablet she holds is 23 feet long. Dont worry though; she hasnt had any trouble holding that tabletyet with her 8 foot index finger.Though America financed and built the pedestal on which the Statue of Liberty stands, the statueitself was a gift from France. In this way the complete work, much like the United States, is a productof both American and French contributions. At one time America was ruled by the British. Thefounding fathers of America chose to fight against Great Britain for the independence of theircountry. France supported America by providing money, men, and weapons of war. Had it not beenfor French contributions during the Revolutionary War, America would not exist in the way that itdoes today; therefore, it is quite fitting that the Statue of Liberty, which represents freedom, came tobeing by a joint American and French effort. On October 28th, 1886, just over one-hundred yearsafter America declared its independence from Great Britain, the Statue of Liberty was completed anddedicated by its designer, Frdric Auguste Bartholdi.Perhaps no person did more to bring the statue into being than Bartholdi. Not only did Bartholdi gainboth French and American approval for the project, he led the French fundraising efforts anddesigned the appearance of the statue. The appearance of the Statue of Liberty is somewhat resultingfrom Libertas, the Roman goddess of freedom. The torch represents how liberty enlightens the world.The seven points or rays coming from the top of the crown represent the sun, the seven seas, theseven continents, and (as with the torch) how liberty enlightens the world. Though much of thestatue was modeled after depictions of goddesses, Bartholdi modeled the face after his mother. Nowthats a Mothers Day gift thats hard to top.Though Bartholdi was responsible for the external appearance of statute, the internal design can belargely credited to innovative designer, Gustave Eiffel. Though Mr. Eiffel is best known for hiscontributions to a tower in Paris that is named after him, he also engineered the internal structurethat holds up the Statue of Liberty. Eiffel chose to use a flexible structure, so that changes in thetemperature and strong winds from the ocean would not cause the statue to crack. Because of Eiffelscrafty design, the Statue of Liberty may sway as much as three inches on a windy day. If the windsexceed 50 miles per hour, the torch may sway five inches. Eiffel is also responsible for including twospiraling staircases on the interior of the statue to help visitors reach the observation point in thecrown.A.Answer the following questions:1. Why is it significant that the Statue of Liberty is a product of both French and American efforts?2. Eiffel chose to use a flexible structure. Explain.3.
