Question

Match each definition to the appropriate term. Locus Interference Linkage Recombination Answer Bank the chromosomal site where a specific gene is located the tendency for genes located in close proximity on the same chromosome to be inherited together the observed double crossover frequency differs from the expected double crossover frequency the process by which a new pattern of alleles on a chromosome is generated

Answer 1

LOCUS:  Locus is a specific, fixed position on the chromosome where a particular gene or genetic marker is located.

INTERFERENCE: The observed double crossover frequency differs from the expected double crossover frequency. In genetics, interference is measured by the coefficient of coincidence during chromosomal crossovers in meiosis. If there is a crossover at one spot on chromosome, This decreases the likelihood of crossover in a nearby spot

LINKAGE: The tendency for genes located in close proximity on the same chromosome to be inherited together. The nearer two genes on chromosomes , lower the chance of recombination between them and more likely inherited together . Markers on different chromosomes are perfectly unlinked

RECOMBINATION: The process by which a new pattern of alleles on a chromosome is generated. It occurs when genetic material is exchanged between two different chromosomes or between different regions on the same chromosome. Type of recombinations are homologous,non homologous and site specific and in prokarotes its conjugation,transformation and transduction
