Chapter 12, Problem 2IQ
Summary Introduction
To determine: The reason why it is not advisable for close relatives to mate and have children regarding the genetic disease.
Introduction: A health problem generated due to irregularities in the genome is known as a genetic disorder. It can be induced due to mutation in a monogenic or multiple polygenic and due to chromosomal abnormality.

- Direction: Explain your answer. A common farming practice is to breed a female horse with a male donkey. The resulk is a very robust animal the mule. Most mules however are sterile, and therefore cannot reproduce. Are horses and donkeys members of the same species? Justify your answer.arrow_forwardwhich of the following statements accurately describes genetic mutationsarrow_forwardBased on Standard NGSS MS-LS3-2: Develop and use a model to describe why asexual reproduction results in offspring with identical genetic information and sexual reproduction results in offspring with genetic variation. In reference to the attached image, can you create a model that shows how it is possible that the twins ended up with such different traits yet have the same parents? Keeping in mind that the twins are a set of fraternal twins. Note:Required a cause-and-effect relationship between parents and offspring with the appropriate mechanism, and Diagram shows genetic recombination as well as inheritancearrow_forward

- Binary fission is a form of asexual reproduction. What is an advantage of asexual reproduction when compared to sexual reproduction? a Asexual organisms are less likely to have mutations in their DNA than sexual organisms are. b An organism that reproduces asexually can reproduce much more quickly than an organism that reproduces sexually. c An asexual organism lives longer than an organism that reproduces sexually. d An organism that reproduces asexually is better equipped to respond to environmental changes than an organism that reproduces sexually.arrow_forwardExplain whether the statement "The normal gene function is required for the viability of the zebrafish." is true, or falsearrow_forwardWhich types of environments/conditions would favor sexual reproduction over asexualreproduction in a species? (select all that apply) Group of answer choices A species that is rapidly expanding into new environments. A species that has accumulated many deleterious mutations An environment that is stable and favorable An environment where a pathogen of a species is rapidly diversifyingarrow_forward
