There are three genes $a,\,b,\,c$. Percentage of crossing over between $a$ and $b$ is $20\%$, $b$ and $c$ is $28\%$ and $a$ and $c$ is $8\%$. What is the sequence of genes on chromosome ?
$b, \,a, \,c$
$a, \,b, \,c$
$a, \,c, \,b$
None of these
Linkage decreases the frequency of
The word 'crossing over' is given by
Crossing over in diploid organism is responsible for
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
