Genetic Screens

Genetic Screens

Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which result in visible changes...

What is Population Genetics?

What is Population Genetics?

A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population breed, they pass down their genes to their offspring. Many of these genes are polymorphic, meaning that they occur in multiple variants. Such variations of a gene are referred to as alleles. The collective set of all the alleles within a population is known as the gene pool.

Chromosomal Theory of Inheritance

Chromosomal Theory of Inheritance

In 1866, Gregor Mendel published the results of his pea plant breeding experiments, providing evidence for predictable patterns in the inheritance of physical characteristics. The significance of his findings was not immediately recognized. In fact, the existence of genes was unknown at the time. Mendel referred to hereditary units as “factors.”

Gene Conversion

Gene Conversion

Other than maintaining genome stability via DNA repair, homologous recombination plays an important role in diversifying the genome. In fact, the recombination of sequences forms the molecular basis of genomic evolution. Random and non-random permutations of genomic sequences create a library of new amalgamated sequences. These newly formed genomes can determine the fitness and survival of cells. In bacteria, homologous and non-homologous types of recombination lead to the evolution of new...

Gene Flow

Gene Flow

Gene flow is the transfer of genes among populations, resulting from either the dispersal of gametes or from the migration of individuals.

Law of Segregation

Law of Segregation

When crossing pea plants, Mendel noticed that one of the parental traits would sometimes disappear in the first generation of offspring, called the F1 generation, and could reappear in the next generation (F2). He concluded that one of the traits must be dominant over the other, thereby causing masking of one trait in the F1 generation. When he crossed the F1 plants, he found that 75% of the offspring in the F2 generation had the dominant phenotype, while 25% had the recessive phenotype.

Summary

This summary is machine-generated.

The rise of the State accelerated human genome evolution by penalizing male aggression and promoting peacefulness. This pacification, exemplified by the Roman Empire, created a gene pool receptive to the spread of Christianity.

Area of Science:

Evolutionary biology
Human genetics
Sociology

Background:

Human genome evolution has accelerated over the past 10,000 years.
This evolution appears linked to social changes, particularly the emergence of State societies.

Observation:

State societies discourage individual male violence, unlike non-State societies that may reward it.
Male aggressiveness is moderately to highly heritable.

Findings:

States tend to reduce violent predispositions in the gene pool, favoring peacefulness and submission.
The Roman state successfully pacified its population, viewing themselves as less violent than 'barbarians'.

Implications:

The Roman state's pacification efforts altered the human gene pool, favoring genotypes associated with reduced aggression.
This genetic shift created a population more receptive to the spread of peaceful ideologies like Christianity.
