Genetic Mapping and Recombination

These flashcards cover key vocabulary and concepts related to genetic mapping, recombination, and human genetics based on the provided lecture notes.

Recombination Frequency

The rate at which genetic recombination occurs, indicating how often different alleles are inherited together.

Map Units

A unit of measurement used in genetics to indicate the distance between genes based on recombination frequency.

Drosophila Genome

The genetic material of the fruit fly, commonly used in genetic studies and research.

Phenotype

The observable traits or characteristics of an organism resulting from the interaction of its genotype with the environment.

Anchor Points

Specific locations on a chromosome used to map other genes or characteristics.

Microsatellites

Short, repetitive sequences of DNA that are highly variable among individuals and useful in genetic mapping.

Single Nucleotide Polymorphism (SNP)

A variation at a single position in a DNA sequence among individuals, useful for studying genetic diversity.

Centimorgan

A unit of measure for genetic linkage, indicating a 1% chance of recombination occurring between two genetic markers.

Consanguinity

The property of being descended from the same ancestor as another person; often used to describe closely related individuals.

Gene Mapping

The process of determining the location and chemical sequence of genes on a DNA molecule.

Human Genome Project

An international scientific research project aimed at determining the base pairs that make up human DNA.

Genealogy Records

Documents and records that trace the lineage and family history of individuals or populations.

Genetic Markers

Specific DNA sequences that can be associated with a particular trait or disease.

Ethical Considerations in Human Genetics

Factors that must be addressed in genetic research involving humans, due to moral and legal implications.

Repetitive DNA

Sequences of DNA that are repeated multiple times in the genome, often found near centromeres and telomeres.

Pedigree Analysis

A genetic representation of individuals and their familial relationships, used to trace traits through generations.
