Alfred Sturtevant
Recombination frequency as a measure of distance between genes:
- Alfred Sturtevant was a student of T.H. Morgan, who conducted research on Drosophila melanogaster (fruit flies).
- Sturtevant observed that the frequency of recombination between two gene loci on the same chromosome is proportional to the physical distance between them.
- This laid the foundation for the concept of genetic mapping, which allows scientists to determine the relative positions of genes on a chromosome.
Significance of recombination frequency:
- Recombination frequency is measured by the percentage of offspring that show recombination between two genes during crossing over.
- Genes that are far apart on a chromosome have a higher recombination frequency, while genes that are close together have a lower recombination frequency.
- By analyzing recombination frequencies, scientists can create genetic maps that show the order and relative distances between genes on a chromosome.
Contribution to genetics:
- Sturtevant's work on recombination frequency and genetic mapping provided important insights into the relationship between genes and chromosomes.
- His research helped establish the chromosomal theory of inheritance, which states that genes are located on chromosomes and are transmitted through the process of meiosis.
- Sturtevant's discoveries have had a lasting impact on the field of genetics and continue to influence research in areas such as genomics and genetic engineering.
