Correct Answer - B
The process of crossing over takes place in pachytene stage of prophase-I of meiosis-I. In this process some genes of two non-sister chromatids of a bivalent are exchanged.
The process of crossing over is depicted
Sister chromatids of one
duplicate chromosome

Some Mendelian crossing experimental results were shown to the students.

1. Genes are located on chromosomes at specific distance and position.  2. The greater this distance, the greater the chance that a crossover can occur between the genes and the greater...

A local post office is to send M telegrams which are distributed at random over N communication channels, `(N > M).` Each telegram is sent over any ch

Correct Answer - B Since lines are more than telegrams, `.^(N)C_(M)` are those lines where telegrams will be sent. So, number of favourable cases = `.^(N)C_(M) xx M!` Total number of...
