The percentage of crossing over will be more if
Linked genes are located far apart from each other
Linked genes are located close to each other
Genes are not linked
Genes are located in a different cell
Who used the frequency of recombination ?
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
Who put forward the “Theory of linkage''
Give scientific reasons : Linkage and crossing over of genes are alternatives of each other.
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
