What is a primary challenge in applying the biological species concept to asexually reproducing organisms?

A. Difficulty in observing morphological features

B. Inability to apply genetic analysis

C. Lack of interbreeding behaviours

D. Similarity in ecological niches

Which of the following best describes the purpose of the binomial system in classifying organisms?

A. Providing a universal method of identifying species based on genetic analysis

B. Assigning two-part scientific names to species for universal recognition and communication

C. Categorising species based on their ecological niches

D. Grouping species based on evolutionary history

Why might two individuals within the same species exhibit different phenotypic traits?

A. They share identical genomes

B. They have experienced different environmental influences

C. They belong to different genera

D. They reproduce asexually

What is a significant implication of chromosomal diversity among species?

A. It prevents genetic mutations

B. It indicates identical evolutionary histories

C. It contributes to the genetic variability and adaptability of species

D. It reduces the complexity of karyotypes

Which factor is NOT typically considered when defining a species using the morphological species concept?

A. Structural features

B. Colour patterns

C. Genetic sequences

D. Body size

During the process of speciation, what is the role of reproductive isolation?

A. It encourages gene flow between diverging populations

B. It prevents interbreeding and maintains species distinctions

C. It increases genetic homogeneity within populations

D. It accelerates the mutation rate within species

Why is genome size not necessarily indicative of an organism's complexity?

A. Larger genomes always correspond to more complex organisms

B. Genome size can be influenced by non-coding DNA and repetitive elements

C. Smaller genomes lack essential genetic information

D. All organisms have genomes of similar sizes

What is the significance of single-nucleotide polymorphisms (SNPs) in the study of genomic diversity?

A. They prevent mutations in DNA sequences

B. They are the most common type of genetic variation among individuals

C. They decrease genetic diversity within a population

D. They are only found in asexual organisms

How does whole genome sequencing contribute to our understanding of evolutionary relationships?

A. By revealing phenotypic characteristics

B. By comparing morphological structures

C. Through the analysis of behavioural traits

D. By allowing comparisons of genetic similarities and differences

In the context of organismal variation, why are no two individuals exactly alike in all traits, even in asexual reproduction?

A. Due to identical environmental conditions

B. Because of genetic recombination during sexual reproduction

C. Owing to mutations and environmental influences

D. As a result of uniform gene expression
