The different dynamics of memes vs. genes - Gene Expression
In particular I wanted to emphasize how genes and memes may transmit The key is to notice the difference between the end states in the. Primacy of consciousness over genes, memes, self and information · Primacy of . ëdeath trapí unless it reinvents its actual relationship with consciousness. . DNA obtained from 23 pairs of chromosomes of a single cell stretches to about two. care, monogamous relationship and polygamous relationship run side by side. Thus Memes and genes may reinforce each other, although sometimes oppose each other. The gene, a length of chromosome, serves as a unit of natural selection. DNA, a self-replicating structure, is different from rival pieces of DNA.
Therefore migration of from the source to the target results in a decrease in the proportion of allele A, which is what is being measured on the y-axis.What is a Chromosome?
Again, the frequency on the y-axis is of the proportion who speak language A in the target zone. The key is to notice the difference between the end states in the memetic scenario. There is a congruence between the shock models for both genes and memes, but a huge difference between them in the gradual scenario.
Concretely I just assumed that the only people in the gradual scenario who spoke the language of the source population would be the migrants themselves.
How are DNA, chromosomes, genes, and alleles related? | Socratic
All of their children would speak the target population language. More abstractly I am implying here that the change in language frequency has some non-linear response dynamics, at a minimum. By this, I mean that what language you speak is a function of the peer groups your parents place you in, as well as their own maintenance of their original language.
In the shock scenario none of this may hold. The migrants are a huge proportion of the population in the initial generation and subsequent generation of migration. The proportion of migrants need not be the majority, rather, the migrant culture simply needs to have critical mass in terms of coherency to seal itself off from native influence.

- DNA, genes and chromosomes
These bases link in a very specific way: A always pairs with T, and C always pairs with G. The DNA molecule has two important properties.
It can make copies of itself. If you pull the two strands apart, each can be used to make the other one and a new DNA molecule.
It can carry information. The order of the bases along a strand is a code - a code for making proteins.
Genes A gene is a length of DNA that codes for a specific protein. So, for example, one gene will code for the protein insulin, which is important role in helping your body to control the amount of sugar in your blood. Genes are the basic unit of genetics. Human beings have 20, to 25, genes. These genes account for only about 3 per cent of our DNA.

The function of the remaining 97 per cent is still not clear, although scientists think it may have something to do with controlling the genes. Chromosomes If you took the DNA from all the cells in your body and lined it up, end to end, it would form a strand million miles long but very, very thin!
To store this important material, DNA molecules are tightly packed around proteins called histones to make structures called chromosomes. The packaging of DNA into chromosomes Human beings have 23 pairs of chromosomes in every cell, which makes 46 chromosomes in total. A photograph of a person's chromosomes, arranged according to size, is called a karyotype.
The sex chromosomes determine whether you are a boy XY or a girl XX.
