- Often, the physical characteristics of genetically identical twins become increasingly different as they age, even at the molecular level. Explain why this is so from the point of view of epigenetics.Define Epigenetic Inheritance Epigenetic inheritance Multiple Choice includes a subset of epigenetlc changes that are passed from parent to offspring across generations. occurs only in female offspring via processes like DNA methy ation is the inheritance of the poténtiol to have DNA changes occur, not the inheritance of actual epigenetic changes is always the result of environmental effects on the cells in an organism involves the inheritance of changes In gene expression thot offects oll traits in an organism Prey 1 of 14 NeBase on your knowledge of DNA, chromosomes and epigenetics and upon examining the picture below, name two epigenetic factors and at least one non-epigenetic factor present on this picture.

- does epigenetics agree or run counter (contradict) to the traditional genetic basis of inheritance or the centraldogma of biology? explain and give your points.Gene Interaction and Epistasis Hair color is due to the presence of melanin. There are two types of melanin produced by melanocytes. One is eumelanin, which is responsible for black (homozygous), brown (heterozygous), and blond (recessive) hair colors. The other is pheomelanin, which is responsible for red hair color. During melanin synthesis, MCR1gene converts pheomelanin to eumelanin. However, a variant of the MCR1 gene (MCR1variant), prevents this conversion. A cross between a blond-haired mother and a red-haired father produced 100% brown-haired children. When they came of age, one child married a double heterozygote, and both were blessed with 7 children; 2 with black hair, 2 with brown hair, 1 with blond hair, and 2 with red hair. Using the 7-step method, determine the genotypes of the P1, the F1, and the F2s. BOX your answers (if handwritten) or HIGHLIGHT your answers (if encoded). STEP 1: ________________________________________________________ STEP 2:…Epigenetics has been described as “inheritance, but not as we know it.” Do you think this is a good definition? Why or why not?

- Define the epigenetic mechanisms - chromatin remodeling bythe addition or removal of chemical groups to histone proteins ?Genetic instability in the form of point mutations, chromosome rearrangements, andepigenetic changes needs to be maximal to allow the development of cancer.(a) With diagrams explain:(i) point mutations (ii) chromosome rearrangement (iii) epigenetic changes. Null alleles (mutant genes) produce no protein product. This is a genetic change. However, epigeneticallysilenced genes also produce no protein product. Howdoes one determine experimentally whether a genehas been silenced by mutation or has been silencedepigenetically?
