S.T.E.M. Article Review
Pochran, S. (2011, Sept. 21). What's on your genes? Tiny genetic switches create big differences. Science News Magazine. Retrieved from https://student.societyforscience.org/article/what%E2%80%99s-your-genes.
This article shows that scientific advances have allowed researchers to significantly modify the physical appearance of offspring through intervention and modification of the genes of the parents. Instead of what is "in" your genes, Pochran (2011) studies modifications which are "on" the genes. She makes this distinction by describing a research study wherein two mice were created; they were genetically identical. They were twins on a genetic level. However, they were physically different in an extreme way. One mouse was small and brown and the other was large, overweight, and orange in color. This experiment, conducted at...
So, even though the two animals can be genetically identical, one might have its dominant genes turned off by methyl groups and thus the creature exhibits the recessive genes without having recessive genes inherited from both parents. Furthermore, researchers in Sydney, Australia found in 2010 that certain diets in the parent could pass on methyl groups to their offspring, creating children that look nothing like their parents. Other factors which can create methyl groups include smoking and drinking alcohol, as well as drug use. Even chemicals which the offspring encounters after their birth can create methyl groups.

Genetics and Development Genetics is a scientific discipline that deals with how individuals inherit their physical and behavioral attributes. Generally, genetics is a branch of biology that deals with the science of heredity, genes, and differences in living organisms. It's the process with which a child inherits traits from his/her parents and the molecular organization and function of genes. The question of what determines the development of a child has been
Genetics and Development: As a discipline of biology, genetics is basically considered as the science of genes, inheritance, and differences in living organisms. Since genes are common characteristics in living organisms, genetics is used in the study of all living systems including plants, humans, domestic animals, bacteria, and viruses. Generally, this biological discipline focuses on the molecular structure and operation of genes whose behaviors are in the context of organisms or
Hence, genetic factors underlie the stability or continuity of psychological traits. Gene Development Mutations play a vital role in genetics, although they cause different disorders living things. Sometimes heredity causes disorders that affect the normal genetic development. Genetic processes control how humans develop from a single cell to adult human beings. Genes control the nervous system cells, and re-growth of skin and hair cells. Genes make humans dynamic organisms capable of
The information is then transcribed into the traits and phenotypes of the offspring depending on the dominance and recessive alleles within the gene (Berg, Tymoczko, & Stryer, n.d). The egg is fertilized by the sperm from the mother and their nuclei fuses together to form a zygote. The zygote contains 23 chromosomes from the mother and 23 from the father. From this combination of genes and the environmental conditions
