In genetics, map units express the distance between

A) chromosomes during metaphase.
B) two loci on a chromosome.
C) alleles.
D) polar bodies.
E) homologous chromosomes.

Map Units

Units used in genetics to measure genetic linkage and represent the distance between genes on a chromosome, correlating with the frequency of recombination.

Loci

Specific fixed positions on chromosomes where genes or genetic markers are located.

Chromosome

Chromosomes are long, thread-like structures made of DNA and proteins, found in the nucleus of most living cells, carrying genetic information in the form of genes.
