Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the core principle?Establishes the relative positions and distances of genes on chromosomes
2. What is the primary methodologies?Genetic mapping (recombination frequencies) and physical mapping (direct DNA analysis)
3. How do scientists find where genes are?They use genetic mapping, looking at how traits are passed down, and physical mapping, looking at the DNA itself with tools like FISH.
4. Why is gene mapping important for health?It helps find genes that cause inherited diseases, so doctors can make tests and treatments.

Locus: The specific physical location of a gene or other DNA sequence on a chromosome.
Recombination Frequency: The likelihood that a crossover event will occur between two linked genes during meiosis.
Molecular Marker: A specific DNA sequence used to identify genes or regions of a chromosome in genetic mapping.
