Percentage value representing how often recombinant offspring appear, directly correlating with gene distance on a chromosome. Map Distance
Measurement, often in map units, indicating the physical separation between genes based on recombination data. Map Unit
Unit equivalent to a 1% recombination frequency, used to express genetic distances between loci. Parental Type
Offspring whose phenotype matches one of the original parents in a genetic cross. Recombinant Type
Offspring displaying new combinations of traits not seen in either parent, resulting from genetic recombination. Genetic Linkage
Condition where genes located close together on a chromosome tend to be inherited together due to low recombination. Independent Assortment
Mendelian principle stating that genes on different chromosomes segregate into gametes independently. Physical Map
Gene mapping approach using DNA sequencing to pinpoint exact nucleotide positions of genes on chromosomes. Genomic Sequencing
Technique for determining the precise order of nucleotides in an organism’s DNA, enabling physical gene mapping. Single Nucleotide Polymorphism
Genomic marker involving a single base change, useful for locating genes and studying genetic variation. Restriction Fragment Length Polymorphism
Variation in DNA sequence detected by restriction enzyme cuts, serving as a marker for gene mapping. Microsatellite
Short, repetitive DNA sequence scattered throughout the genome, valuable for identifying gene locations. Crossover
Exchange of genetic material between homologous chromosomes, leading to new allele combinations in offspring. Tester
Individual with a known genotype used in crosses to reveal the genotype of another organism. Homozygous
Genetic condition where both alleles at a locus are identical, either dominant or recessive.
