The exchange of genetic material between homologous chromosomes during meiosis

Which of the following events occurs during genetic recombination?

Crossing over

What is the primary function of DNA?

Store and transmit genetic information

To monitor the expression of the inserted gene

What is the primary purpose of recombinant DNA technology?

To manipulate and modify the genetic material of organisms

Which of the following is an application of recombinant DNA technology in medicine?

Developing vaccines and therapeutic proteins

It is the all copies of all the genes in a population. The combination of all the genes (including alleles) present in a reproducing population or species.

Gene Pool

It refers to how common an allele is in a population or how frequent a certain trait or characteristic occurs in population.

Allele Frequency

This is the change in allele frequency because of chance.

Genetic Drift

What is the 2 examples of Random Drift.

Bottleneck effect & Founder effect

A change in the frequency of gene variants, alleles, in a population, typically occurring over a relatively short period of time.

Microevolution

Who was the scientist that according to him all species descended from only a few life forms that had been modified over time.

Darwin

It refers to the species that changed over time, giving rise to new species and sharing common ancestor.

Evolution

It is the blue prints for making an organism, and hold information about its conceivable aspects.

Genes

Darwin uses the phrase ______ instead of evolution.

Descent with Modification

It is when the species adapts to its environment, thanks to its specific genetic makeup

Natural Selection

Which scientist proposed the theory of evolution by natural selection?

Charles Darwin

What term describes the anatomical structures that have similar underlying structures but different functions in different species?

Homologous structures

What type of evidence for evolution involves studying the similarities in DNA sequences among different species?

Molecular biology

Which of the following is an example of a homologous structure?

The wings of a bat and the arms of a human

Which of the following is the correct representation of a phylogenetic tree?

A tree diagram that shows the evolutionary relationships between species.

What is the main difference between homologous and analogous structures?

Homologous structures have a common evolutionary origin, while analogous structures do not.

Which of the following is the most commonly used molecule for molecular comparisons in evolutionary studies?

DNA and Protein

Birds and dinosaurs share a common characteristic of:

Hollow bones

It is a features of different species that are similar in function but not necessarily in structure and which do not derive from common ancestral feature and which evolved in response to a similar environmental challenge.

Analogous structure

Which of the following provides evidence for the relatedness of different species based on their geographic distribution?

Biogeography

What type of evidence for evolution involves studying the preserved remains or impressions of organisms from past geological periods?

Fossil record

What is the term for the study of evolutionary relationships among organisms based on shared characteristics?

Phylogeny

What type of evidence is commonly used to infer evolutionary relationships among organisms?

DNA/protein sequences

Which of the following provides evidence for evolution by showing a pattern of common descent from a shared ancestor?

Homology

What is the term for the science of classifying organisms based on their structural and developmental characteristics?

Taxonomy

Which of the following is a structural characteristic used in classifying living things?

Body shape and size

How do scientists use DNA sequences in classifying living things?

To infer evolutionary relationships among species

In cladistics, what is the term for a group of organisms that includes an ancestor and all of its descendants?

Clade

Which taxonomic level is typically characterized by the presence of synapomorphies?

Family

What is the term for the analysis of shared derived characters to determine evolutionary relationships?

Cladistics

It is based on evolutionary history or pattern of descent.

phylogenetic classification

It is a method that is artificial since organisms are classified based on morphological similarities and not on evolutionary relationship .

Linnean Method

What is the best Explanation of Taxonomy

The theory and practice of classifiying organism

Play as systematic tools that classify organisms based on their common ancestry.
