Humans vary in their ability to taste the bitter chemical compound phenylthiocarbamide ( PTC ). The taster phenotype is dominant to the non-taster phenotype. Researchers tested the PTC taster phenotype of individuals from an isolated population. In the sample, 780 individuals were able to taste PTC and 70 individuals were not able to taste PTC .Assuming the population is in Hardy-Weinberg equilibrium, what is the frequency of the non-taster allele

Answers

Answer 1

Answer:

The frequency of the recessive allele, t is f(t) = q = 0.29.

Severe acute respiratory syndrome (SARS) is an illness caused by a coronavirus. Symptoms, including a high fever, headaches, and body aches, typically occur two to seven days after infection by the virus. This information suggests that the reproductive cycle of the SARS virus is - lysogenic, because the virus is a coronavirus. lysogenic, because the virus is a coronavirus. lysogenic, because the virus primarily affects older people. lysogenic, because the virus primarily affects older people. lytic, because the virus causes respiratory illness. lytic, because the virus causes respiratory illness. lytic, because of the quick onset of symptoms after infection.

Answers

Answer:

lytic, because of the quick onset of symptoms after infection

Explanation:

As seen in the question above, the SARS virus tends to develop symptoms very quickly when it is infecting a person. This speed in the development of symptoms is a characteristic of the lytic cycle, in relation to the reproductive cycle of viruses. This is because in the lytic cycle, a virus can infect many cells at once, which accelerates the development of the disease. This cycle allows the virus to use all of the cell's biological machinery to reproduce more copies of the virus. When these copies are ready, the virus causes the destruction of the host cell and the release of new viruses to other cells, where the whole process will be repeated. This is all done very quickly.

The lysogenic cycle does not cause the rapid infection of thousands of cells, since it is necessary that there is an adaptation between the DNA of the cell and the DNA of the virus. This slows down the infection process and, therefore, symptoms appear more slowly.

Answer:

lytic, because of the quick onset of symptoms after infection

What is the genotype for a h0m0zygous recessive for freckles? ff

What is the phenotype? No freckles

What is the genotype for a heterozygous individual for freckles? Ff

What is the phenotype? Freckles.

Each individual has two alleles for a given gene.

For example, the allele dimples are dominant. How would you represent this allele? With capital letters, for example, DD.

The allele for no dimple is recessive. How would you represent this allele? With lowercase letters, for example, dd.

The allele for brown eyes is dominant. How would you represent this allele? With capital letters, for example, BB.

The allele for blue eyes is recessive. How would you represent this allele? With lowercase letters, for example, bb.

PP: h0m0zygous dominant; Yy: heterozygous; Ss: heterozygous; bb:h0m0zygous recessive; FF: h0m0zygous dominant

Explanation:

Every being, such as plants, animals, or humans, have two different copies of a gene. These are alleles. These copies can be dominant or recessive.

Dominant genes are the ones that we will see. They "hide" the recessive gene. Recessive genes are the ones that we will only express if the two alleles are recessive since there is no dominant gene that hides the other.

Genotype is the genes that an individual or animal has. We can not see it. For example, a person can have a dominant trait for blue eyes and a recessive trait for brown eyes (Bb)s. In other words, it is the genetic information that a person carries. The phenotype is what we can see of a trait. Following the previous example, the dominant trait is blue eyes, and the recessive is brown, so the gene that will express itself is blue eyes, and we will able to see it.

The pair of alleles can be h0m0zygous and heterozygous. H0m0zygous is when the two traits are the same, for example, BB or bb. Heterozygous is when the traits are different, like, Bb.

Pea plants have two flower varieties where purple is dominant over white. The dominant trait, we represent it with a capital letter, in this case, P, because it is the first letter in purple. The recessive trait we represent it with a lowercase letter, in this case, p.

The genotype for a h0m0zygous dominant plant would be PP. We have to remember that the genotype is the information that the plant carries. If this information is h0m0zygous, it means the two alleles are the same, and if they are both dominant, we write capital letters. The phenotype is what we can see of the information; the gene that it is expressed, in this case, would be the color purple.

A h0m0zygous recessive plant has two alleles with the same information, and as they are recessive, we write two lowercase letters (pp). The genotype would be white plants since there is no dominant allele that covers the recessive one.

In a heterozygous plant, the traits are different. We have the dominant trait purple (P) and the recessive trait white (p). The dominant is the one that will express itself and the one that we will be able to see, see in a purple plant.

The following questions are similar to the first one. We know that freckles are a dominant trait, so we use a capital letter to represent it (F) and a lowercase letter to portrait the recessive trait, which is no freckles (f).

A h0m0zygous dominant means that the two alleles are the same and that one does not hide the other so, the genotype would be FF, and the phenotype would be a person with freckles.

If the person is h0m0zygous recessive, it means that it has the same traits, but one allele does not hide the other. The genotype would be ff, and the phenotype would be no freckles.

In the last case, the person is heterozygous, which means that it has one dominant and one recessive allele. The dominant allele will express itself; the genotype would be Ff, and the phenotype freckles.

In the following questions, we know that we represent dominant alleles with capital letters and recessive ones with lowercase letters, if it is a dominant allele for brown eyes, we write BB, taking the first letter of the dominant trait, in this case, brown. If it is a recessive trait, we write lowercase letters, in this case, bb for blue eyes.

In the last set of questions, we have to observe the letters to find the genotype.

PP, FF: the two letters are the same, which means that the allele is h0m0zygous. Also, they are both in capital letters, so they are dominant traits. Yy, Ss: the two letters are different, one is in capital letters, and the other is not. The allele is heterozygous. bb: the two letters are the same, so they carry the same information. They are h0m0zygous. Both of them are in lowercase, so they are recessive alleles.
