If two genes are situated at some distance on chromosome such that crossing over can easily occur. Which of the following option will be true?

The correct option is A $\frac{2}{4}$ of parental combination,
$\frac{2}{4}$ of new combination

If two gene is located on the chromosome at some distance and is not showing linkage property then we can conclude that they can be separated for each other during the process of crossing over. It is the phenomenon in which the chiasmata formation takes place due to which the exchange of gene takes place between parental chromosome and daughter chromosome strand. So out of four chromosome, 2 will have parental combination while rest two will have the new set of combination due to chiasmata formation.

So the correct option is '2/4 of parental combination,2/4 of new combination'.
