根据第二段中的“According to Dawkins, while genes are the pieces of biological information from our parents which determines our appearance and how we grow, memes are units of cultural information — ideas and beliefs — that “pass from brain to brain”. (根据道金斯的说法,基因是来自父母的...
1. Why do genetic mutations happen? 2. What factors do they depend on? How can a non-genetic factor like nutrition have effects passed down over generations? How do genes and education affect the brain? What is the difference between heredity and evolution?
but these traits were also passed on to their offspring through two subsequent generations. Although difficult to prove by experiments on humans for ethical reasons, there is some reason to
What genes are inherited from mother only? Mom is homozygous healthy, and dad is hemophilic. What is the percent chance of having a hemophilic baby? Discuss your family history of genetic disorders, how these disorders are passed on through generations, and what types of testing can be done ...
The concept of epigenetics is fascinating and looks at how factors such as prenatal nutrition, diet and stress can all influence the genes which are passed on through generations of the same family. How to increase the chances of having fraternal triplets?Here’s how to increase the chances ...
While all of this might sound mystical, it’s not so different from the scientific idea of epigenetics—the study of howexperiences and traumas can be passed down through generations via how genes express themselves. Just as stress responses from trauma can alter our cells’ gene expression, me...
There are also other ways our life stories can be passed down through generations, besides being inscribed in our DNA. "Epigenetics" is a relatively new area of science that can reveal how intertwined nature and nurture can be. It looks not at changes to genes themselves, but instead at the...
If you are intelligent and have children with someone who is intelligent, will your kids be smart? In this lesson, we will examine the aspects of intelligence that seem to be passed down through the generations, as well as how life experiences play a pa...
How do you know if you have dominant or recessive genes? For example, if a trait tends to be directly passed from parent to child, thenthe odds are pretty good that the trait isa dominant one. If a trait skips generations or pops up out of nowhere, then the odds are pretty good that...
A mutation changes one of the two genes in a harmful way. Assume that a child receives this mutant gene from the father. The mother contributes a normal gene, so it may have no effect on the child (as in the case of the "short" pea gene). The mutant gene might persist through ...
