Herpes simplex virus 1 (HSV-1), infects humans and produces most cold sores. The virus is contagious. Herpes simplex can be spre

ad through contact with saliva, such as sharing drinks. HSV-1 persists in the body by becoming latent and hiding from the immune system in the cell bodies of neurons. After the initial or primary infection, some infected people experience sporadic episodes of viral reactivation or outbreaks. How would scientists with Viewpoint #1 respond to the description the herpes virus? A) A virus is alive because it causes disease. B) A virus is not living; it responds to chemical changes in the environment. C) A virus is alive; it can respond and/or adapt to changes in the environment. D) A virus is not living; it has no genetic material and does not undergo division.

Ans. (C). A virus is alive; it can respond and/or adapt to changes in the environment.

Viruses are connective links between living and non-living things as they show characteristics of both. Viruses can be considered as living inside the host body, where they use host machinery to replicate their own genetic material and make their progeny.

Viruses can be respond to changes in their surrounding environment as other living organisms and adapt to those changes. For example, herpes simplex virus 1 becomes adapt to responses shown by immune system of host.

Thus, the correct answer is option (C).

[Chapter 3-4] A cross was carried out between the following two pureline parental strains:Parent 1: A/A; b/b; D/D; e/e; F/FParen
andrew-mc [135]

Answer:

Following the selfing of the F1 from the cross between the two parental strains, what proportion of the F2 individuals will phenotypically resemble either one of the two parental lines?

= 7.03% of F2 progeny will resemble parent 1

= 2.34% of F2 progeny will resemble parent 2.

Explanation:

Parent 1: AA; b/b; D/D; e/e; F/F

Parent 2: a/a; B/B; d/d; E/E; f/f

F1 Progeny: A/a; B/b; D/d; E/e; F/f

knowing that the F1 progeny is selfed, the possible gamete outcomes are:

ABDeF , ABDEf, ABdeF, ABdEf

AbDeF , AbDEf , AbdeF , AbdEf

aBDeF , aBDEf , aBdeF , aBdEf

abDeF , abDEf , abdeF , abdEf

All gametes are either eF or Ef (the two parental genotypes) and never EF or ef.

At the A, B and D loci, the F1 are heterozygotes. Therefore, in the F2 progeny, for each locus, 3/4 of the progeny will have the dominant trait while 1/4 will have the recessive phenotype. Further, 1/2 of all F2 progeny will have the haplotype eF and the other half will be Ef.

<u>Proportion of progeny resembling Parent 1: </u>

Parent 1 has the Phenoytpe AbDeF. As previously discussed, 3/4th of all F2 progeny has the phenotype A, 1/4th of F2 progeny has the phenotype b, 3/4th of F2 progeny has the phenotype D and 1/2 of F progeny has the phenotype eF.

Thus, the proportion of progeny resembling Parent 1

= 3/4 x 1/4 x 3/4 x 1/2 = 0.0703125

= 7.03% of F2 progeny will resemble parent 1.

<u>Proportion of progeny resembling Parent 2</u>:

Parent 2 has the Phenoytpe aBdEf. As previously discussed, 1/4th of all F2 progeny has the phenotype a, 3/4th of F2 progeny has the phenotype B, 1/4th of F2 progeny has the phenotype d and 1/2 of F progeny has the phenotype Ef.

Thus, Proportion of progeny resembling parent 2

= 1/4 x 3/4 x 1/4 x 1/2 = 0.0234375

= 2.34% of F2 progeny will resemble parent 2.

First-division nondisjunction will only yield gametes with an extra chromosome, whereas second-division nondisjunction will only
statuscvo [17]

False

Explanation:

  • During the meiosis, the cell is dividing two times and chromosomes are getting replicated. In this process, there can be errors. One of those errors is called nondisjunction.
  • As a result of the meiosis one, the cell gets divided into two cells and each will carry 23 chromosomes each. At this stage, These chromosomes are connected in the form of sister chromatids. During the meiosis two, these sister chromatids will pull apart and form four cells. Each one will be haploid cells. In meiosis one, chromosomes will undergo crossing over so this separation of chromosomes in the second meiosis is know as disjunction. However, in this process of separation, the chromosomes do not need to get distributed correctly. The errors that happened in this process are known as nondisjunction.
  • In humans, meiosis will happen and form sperms or eggs( gametes) which are haploid cells and later they combined to form a zygote which is the diploid cell.
