Questions and Answers

If a scientist is studying the complete set of genetic material of a newly discovered bacterium, what is the scientist analyzing?

The bacterium's locus.
The bacterium's genes.
The bacterium's chromosomes.
The bacterium's genome. (correct)

Which of the following best describes the relationship between genes and a genome?

Genes are segments of DNA that code for specific traits; a genome is the complete set of an organism's genetic material. (correct)
Genes are the specific location of DNA on a chromosome; a genome is a segment of DNA.
A genome is the specific location of a gene on a chromosome; genes are the mechanism for sexual reproduction.
A genome is a segment of DNA that codes for a specific trait; genes are all of the organism's genetic material.

In a genetics study, researchers are trying to pinpoint the exact location of a particular gene responsible for a certain trait. What specific term are they trying to identify?

The gene pool.
The genome.
The locus. (correct)
The chromosome arm.

A population of hydras reproduces asexually. What is the most likely outcome regarding the genetic diversity of this population over time, assuming no mutations occur?

Genetic diversity will remain constant, with all individuals being genetically identical. (B) Signup and view all the answers

Why is genetic variation important for the long-term survival of a species in a changing environment?

Consider a plant species that can reproduce both sexually and asexually. Under which conditions would asexual reproduction be more advantageous for the plant's survival?

In a stable environment where the plant is well-adapted. (D) Signup and view all the answers

Suppose a new disease is introduced into a population of organisms that reproduce asexually. What is the likely outcome compared to a sexually reproducing population?

The asexually reproducing population is more likely to suffer widespread mortality due to lack of genetic variation. (B) Signup and view all the answers

A researcher discovers a new organism in a remote area. After analyzing its method of reproduction, they find that the offspring are genetically identical to the parent. What type of reproduction does this organism use, and what benefit might this provide in its specific environment?

Asexual reproduction; ensures traits suited to a stable environment are passed on. (B) Signup and view all the answers
