Frequency of recombination between gene pairs on same chromosome as a measure of the distance between genes to map their position on chromosome, was used for the first time by
Henking
Thomas Hunt Morgan
Sutton and Boveri
Alfred Sturtevant
The distance between two genes in a chromosome is measured in cross-over units which represent
Two genes $R$ and $Y$ are located very close on the chromosomal linkage map of maize plant. When $RRYY$ and $rryy$ genotypes are hybridized, then $F_{2}$-segregation wii show
Frequency of crossing over in a chromosome is an index of
The tendency of genes to remain together during the process of inheritance is known as
Discuss in detail the contributions of Morgan and Sturtevant in the area of genetics.
