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
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
On the basis of Mendel's work which of the following laws were formulated?

$II.$ Segregation
$III.$ Incomplete dominance
$IV.$ Independent assortment
Choose the correct option
The recombination frequency between the genes $a\, \& \, c$ is $5 \,\% \,, b\, \& \,c$ is $15 \,\%,\, b\, \& \,d$ is $9 \%, \,a\, \& \,b$ is $20 \%$ , $c\, \& \,d$ is $24 \%$ and $a \, \& \,d$ is $29 \%$. What will be the sequence of these genes on a linear chromosome?
Crossing over is
Crossing over in diploid organism is responsible for
