Textbook Question

A(n) ___________________ is a genetic variant of the same species.

Verified step by step guidance

Identify the term that describes a genetic variant within the same species.

Consider the context of genetic variation and how it applies to species.

Recall that within a species, genetic differences can arise due to mutations, recombination, or other genetic processes.

Think about terms used in genetics to describe variations, such as 'allele', 'strain', or 'subspecies'.

Determine which term is most commonly used in microbiology to describe a genetic variant of the same species.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Genetic Variant

A genetic variant refers to a change in the DNA sequence that can occur within a species. These variations can manifest as single nucleotide polymorphisms (SNPs), insertions, deletions, or larger structural changes. Genetic variants contribute to the diversity within a species and can influence traits, behaviors, and susceptibility to diseases.

Species

In biological classification, a species is defined as a group of organisms that can interbreed and produce fertile offspring. Members of the same species share common characteristics and genetic makeup, which distinguishes them from other species. Understanding the concept of species is crucial for studying biodiversity and evolutionary relationships.

Allele

An allele is a specific version of a gene that can exist at a particular locus on a chromosome. Alleles can be dominant or recessive, and they contribute to the genetic variation observed within a species. The combination of alleles inherited from parents determines an organism's traits, making them essential for understanding genetic diversity and inheritance.
