Ancien Régime and the Transition to Parliamentary Monarchy

Understanding the Ancien Régime

The Ancien Régime was a system characterized by:

• Political Absolutism: Kings and queens held absolute power.
• Social Hierarchy: Society was divided into estates with unequal privileges.

• Bourgeoisie and Peasants: The bourgeoisie criticized the privileges of nobles and clergy, advocating for social recognition based on merit. Peasants opposed the manorial system and excessive taxes.
• Economic Challenges:

Basic Concepts

• Trait: An inheritable characteristic of an organism.
• Gene: A DNA segment containing information that controls a specific trait.
• Allele: A variant form of a gene, often arising from mutations, contributing to hereditary variations.
• Locus (pl. Loci): The specific location of a gene on a chromosome.

Zygosity

• Homozygous Organism: Possesses identical alleles for a given gene (e.g., AA or aa).
• Heterozygous Organism: Possesses different alleles for a given gene (e.g., Aa).

Allele Interactions

• Dominant Allele: An allele that expresses its phenotype regardless of the paired allele.
• Recessive Allele: An allele that expresses its phenotype only when paired with an identical allele.

Genetic Inheritance Patterns

• Dominance (Dominant

• Nucleoside: A part of a nucleotide made up of one sugar (ribose or deoxyribose) and one nitrogenous base (pyrimidine or purine) joined together by N-glycosidic bonds.
