Chapter 36, Problem 1TYU

Summary Introduction

Introduction:

Parthenogenesis is a mode of asexual reproduction in which an egg develops into an embryo without fertilization.

Expert Solution & Answer

Answer to Problem 1TYU

Correct answer:

Only a single parent is required for parthenogenesis, as fertilization is not needed. Hence, fertilization is not required for the development of an egg into an embryo. Therefore, option (D) is correct.

Explanation of Solution

Reason for the correct statement:

Parthenogenesis is observed in lower plants and animals. The egg or gamete produced by the female develops into a complete organism without fusion with the male gamete.

Option (D) is given as “An egg develops without being fertilized”.

“In parthenogenesis, an egg develops without being fertilized”. Thus, it is the right answer.

Hence, option (D) is correct.

Reasons for the incorrect statements:

Option (A) is given as “An individual may change its sex”.

An individual changing its sex is not parthenogenesis; it is called sequential hermaphroditism. Therefore, it is a wrong answer.

Option (B) is given as “Groups of cells grow into new individual”.

In parthenogenesis, a single egg develops into a complete organism, not from the groups of cells. Therefore, it is the wrong answer.

Option (C) is given as “An organism is first a male and then a female”.

An organism that develops as a male, and then develops into a female is called a protandrous hermaphrodite. Therefore, it is the wrong answer.

Hence, options (A), (B) and (C) are incorrect.

Conclusion

Parthenogenesis is an asexual mode of reproduction in which an organism develops from an unfertilized egg.

Svp je voulais demander l aide pour mon exercice

Imagine that you are a clinical geneticist. Your colleague is an oncologist who wants your help explaining the basics of genetics to their patient, who will be undergoing genetic testing in the coming weeks for possible acute myeloid leukemia (AML) induced by the radiation she had several years ago for breast cancer. Write a 1,050- to 1,225-word memo to your colleague. Include the following in your memo: An explanation of the molecular structure of DNA and RNA, highlighting both similarities and differences A description of the processes of transcription and translation An explanation of the differences between leading and lagging strands and how the DNA is replicated in each strand Reponses to the following common questions patients might ask about this type of genetic testing and genetic disorder: Does AML run in families? What genes are tested for?

Respond to the following in a minimum of 175 words: What are some potential consequences that could result if the processes of replication, transcription, and translation don’t function correctly? Provide an example of how you might explain these consequences in terms that patients might understand.
