recombinant chromosome
A chromosome formed by crossing over between homologous chromosomes during meiosis.
Full Definition
A recombinant chromosome is one that contains a combination of genetic material from both parental homologs as a result of crossing over during meiosis. This natural process of genetic recombination creates new combinations of alleles along chromosomes, contributing to genetic diversity in offspring. In reproductive genetics, understanding recombination is crucial for genetic linkage analysis, predicting inheritance patterns for closely linked genes, and interpreting results from genetic testing that relies on linked markers.
Usage
Usage note: Distinguish from 'derivative chromosome' which refers to structurally rearranged chromosomes.
