How many types of gametes will be produced by a $O$ Drosophila having following arrangement of
two genes ($y*$ and $w*$) on $X-$chromosome?

What is recombination ? Discuss the applications of recombination from the point of view of genetic engineering.

The frequency of recombination between gene pairs on the same chromosome as a measure of the distance between genes was explained by

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 ?

Crossing over in diploid organism is responsible for
