Think about how the biological mechanisms of epigenetics differ from those of genetics (which is evolution, or gene mutation over many, many generations). Do epigenetics mutate the sequence of our DNA like evolution does? Do they take hundreds of generations to show up like evolution does? If evolution is the driving force behind genetics, what is the driving force behind epigenetics? Could we conclude that it's our environment?

Expert Solution

Biological mechanism of epigenetics differ from genetics are-

Epigenetics is the study of heritable changes in phenotype without permanent changes to the DNA of the gene.while genetics is the study of heritable changes in phenotype caused by permanent DNA changes within a particular gene .epigenetics describe passing on the way the genes are used while traditional genetics describe the way the DNA sequence in our genes are passed from one generation to the next.

Epigenetics form an octameric histone while while DNA can wrape around.

Example of epigenetics are methylation ,histone modification.

do epigenetics mutate the sequence of our DNA like evolution does-

Epigenetics donot involve changes to the underlying DNA sequence- a change in phenotype without a change in genotype which is turn affects how cells read the genes epigenetics mutate donot similar to evolution.

Do they take hundreds of generation to show up like evolution does-

Epigenetics reports direct transmissions of features to the next generation.

Driving force behind genetics-

There are four main forces of evolution behind genetics i.e mutation ,gene flow,genetic drift,and natural selection .mutation generate new genetic varriation in a gene pool ,gene flow and genetic drift alter allel frequency in a gene pool.

Driving force behind epigenetics

Immunesuppression is the predominant driving force for morbidity and mortality ,immune paralysis is reprogramming in immune and proginator cells.

could conclude it is in environment-

Epigenetics modify the environment in the broad sense .the cells receive all types of signals informing it about it environment so it is specilizing during development.

Describe development from toddlerhood through adolescence from a biological perspective (physical development, genetics, epigenetics, or evolutionary psychology). Provide five (5) examples to illustrate the biological component of development. You must provide at least one example from each chapter (chapters 4 - 8). Explain how each example impacts development.

1. List the mechanisms of evolution and how each affects genetic diversity. The mechanisms of evolution were Natural Selection, Mutations, genetic drift, and Gene flow. 2. What are the conditions that must be met in order for the Hardy-Weinberg Equilibrium Principle to exist within a population?

The three major mechanisms of evolution differ in how they work, and as a result often have different effects on a population.

Part B - Comparing natural selection, genetic drift, and gene flow The three major mechanisms of evolution differ in how they work, and as a result often have different effects on a population. Review your understanding of natural selection, genetic drift, and gene flow by sorting the statements below into the correct bins. Drag each statement into the appropriate bin depending on whether it applies to natural selection, genetic drift, or gene flow.

Evolution, in the biological sense, is NOT described by which of the following? A. It is defined simply as change over time. B. It is genetic change in populations over time. C. It requires genetic variation in the population. D. It requires differential survival of individuals based on genetic factors. E. It is described by all of the above. Advantages of studying molecular variations include all of the following EXCEPT: A. molecular data directly reflect genetic differences. B. molecular data...

How did Lamarck’s theory of evolution DIFFER from that of Darwin’s? Lamarck believed that Earth was old enough to provide a sufficient time scale for the process of evolution. Lamarck believed that the environment played a significant role. Lamarck believed that characteristics acquired during an organism’s lifetime could be passed on to the next generation. Lamarck believed that acquired character during an organism’s lifetime could not be passed on to the next generation.
