The relationship between evolutionary time and the similarity of genes in two species?
The longer the evolutionary time between two species, the more dissimilar their genes are likely to be due to accumulating mutations. Conversely, species that share a more recent common ancestor are expected to have more similar genes because they have had less time to diverge through evolution.
A particular plant species is pollinated by a certain insect species. The insct species edepends on the plant species for food. Which term describes how this relationship forms?
Co-adaptation which can occur between interacting genes or structures within an organism or in this case between two or more interacting species. ( the plant and the insect ) Give me a Like

What can genes tell us about an organism's evolutionary history?
Genes provide crucial insights into an organism's evolutionary history by revealing the genetic similarities and differences between species. By comparing DNA sequences, scientists can trace lineages, identify common ancestors, and estimate the time of divergence between species. Additionally, genetic variations and mutations can indicate how organisms have adapted to their environments over time. Overall, the study of genes helps reconstruct the evolutionary tree of life, illustrating how species have evolved and diversified.
What is different in phenotypes of an individual from those in the same species?
Phenotypes are the characteristics of the genes that are most dominant, and can represent themselves. Species have many different genes for example, you dont have the exact same genes as your best friend, and thus, producing different phenotypes which is why you look different... However, you do have may similar genes that make you part of that species.
What can be gained by species mating with other closely associated species bringing new genes into their own population from the others?
mutation
What is the difference between paralog and ortholog genes in terms of their evolutionary relationship and functional divergence?
Paralog genes are duplicated genes within the same species, while ortholog genes are genes that are present in different species but share a common ancestor. Paralog genes evolve through gene duplication events within a species, leading to functional divergence, while ortholog genes evolve through speciation events, maintaining similar functions across different species.
What is the difference between orthologous and paralogous genes in terms of their evolutionary relationship and functional divergence?
Orthologous genes are genes that originated from a common ancestor and diverged due to speciation, while paralogous genes are genes that originated from gene duplication within the same species and diverged due to mutations. Orthologous genes have similar functions in different species, while paralogous genes may have different functions within the same species.
What is cisgenic organism?
A cisgenic organism is one that has been genetically modified using genes from a closely related species that could potentially be bred in nature. This is different from transgenic organisms, which involve genes from unrelated species. Cisgenic modification is considered by some to be more acceptable and akin to traditional breeding methods.
What is the difference between orthologs and homologs in terms of evolutionary relationships between genes or proteins?
Orthologs are genes or proteins in different species that evolved from a common ancestor through speciation, while homologs are genes or proteins in the same species that share a common evolutionary origin. In other words, orthologs are related through a divergence of species, while homologs are related within the same species.
What is the difference between homologs and orthologs in terms of evolutionary relationships between genes?
Homologs are genes that share a common ancestry, while orthologs are homologous genes that are found in different species due to speciation events. In other words, homologs are genes that are related through evolution, while orthologs are homologs that have been separated by the divergence of species.
What is the difference between a linked and unlinked gene?
Linked genes are located close together on the same chromosome and tend to be inherited together. Unlinked genes are located on different chromosomes or are far apart on the same chromosome and are inherited independently. Crossing over during meiosis can break the linkage between linked genes, allowing for new combinations of alleles to be formed.
How can DNA show some evidence of evolution?
DNA can provide evidence of evolution through the presence of homologous genes, which are genes shared among different species that originated from a common ancestor. Additionally, the similarity of DNA sequences between related species can show how closely they are related evolutionarily. Mutations in DNA can also accumulate over time, leading to genetic variation that drives evolutionary change.
How can molecular evidence show how closely related species are to each other?
Well, using molecular techniques we can now sequence and evaluate the genomes of organisms. So if we know the genes in a human, a monkey, and a carrot, for example, then we can see genetically which organism is more related to the other. Mind you Darwin didn't even know what genes were when he did his research in the Galapagos
What is the difference between paralogous and orthologous genes in terms of their evolutionary relationships and functions?
Paralogous genes are genes that arise from a gene duplication event within the same species, leading to multiple copies of a gene with similar functions. They can evolve new functions over time. Orthologous genes, on the other hand, are genes that are derived from a common ancestor through speciation, leading to genes with similar functions in different species. They typically retain the same function across different species.
Help I need to know by the17th march for hw What is the link between two species called?
genes or genus
What is phylogenetic relatedness?
Phylogenetic relatedness refers to the degree of evolutionary relationship between different organisms based on their shared genetic ancestry. It is often represented in a phylogenetic tree, which shows how species are connected through common ancestors. The closer the branches on the tree, the more closely related the organisms are believed to be.
