How does the duplication of genes and /or genomes allow for the evolution of genomes?
The genes which evolved by duplication are called as paralogous genes. These genes have similar structure and function.
A lot of genome in living organisms have originated by duplication. Genes have duplicated themselves and increases in copy number. Further mutation in the duplicated genes have led to the origin of new genes with similar structure and function. For example, hemoglobin and myoglobin and immunoglobulin, all belong to globin gene family. Their structure is quite similar. The function is also quite similar like the function of hemoglobin is to carry oxygen to different parts of the body and myoglobin is to carry oxygen to the muscle cells.

1.Which of the following does NOT contribute to the possibility of a gene duplication event occurring? a. Low sequence homology b. Homologous Recombination c. Short, repetitive DNA sequences d. Misalignment e.None of these are correct 2.Which term is not correctly matched with its definition? a. Analogous structures - similar structures as a result of convergent evolution b.

Describe the role of gene duplication which leads to the evolution of autologous genes within a gene family. What are some of the benefits of having such a family? What might be some drawbacks from a research perspective? Describe the evolution of the expressive eye phenotype of domesticated dogs that is distinct from ancestral wolves. Which structures give dogs these expressive eyes? What was the purpose/advantage of the adaptation? How did humans likely provide the driving force for this evolution...
1. The virus repressor protein A) controls the prophage's lytic genes but not the incoming genomes of the same virus. B) does not control the prophage's lytic genes but does control the incoming genomes of the same virus. C) controls both the lytic genes on the prophage and prevents an incoming virus of the same type. D) has different actions in different situations. 2. The primer for retrovirus reverse transcription is a specific A) tRNA encoded by the cell. B)...

What does modular domain structure of proteins in eukaryotes allow for in terms of evolution?
How does cosmic Evolution relate to Darwin theory of evolution?
Explain the two main mechanisms of gene duplication (not polyploidy) described in class. How can you identify which mechanism produced a given gene? That is, describe all of the differences you would expect. What is the significance of gene duplication to evolution?
