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

Verified step by step guidance

1. Understand the question is asking for a term that describes a genetic variant within the same species.
2. Recall that in microbiology and genetics, a genetic variant within the same species is often referred to as a 'strain' or 'variant'.
3. Consider the context: a 'strain' is a genetic variant or subtype of a microorganism (such as bacteria or viruses) within the same species.
4. Confirm that the term 'strain' fits the definition of a genetic variant of the same species, commonly used in microbiology.
5. Therefore, the correct term to fill in the blank is 'strain'.

Key Concepts

Genetic Variation

Genetic variation refers to differences in the DNA sequences among individuals within the same species. These variations can result from mutations, gene flow, or sexual reproduction, leading to diverse traits and adaptations.

Species and Intraspecies Variation

A species is a group of organisms capable of interbreeding and producing fertile offspring. Within a species, genetic variants exist, representing different forms or alleles that contribute to diversity but do not define separate species.

Definition of an Allele

An allele is a specific version of a gene found at a particular locus on a chromosome. Alleles are genetic variants within a species that can influence traits and are inherited from parents to offspring.
