Question

In Pisum sativum there are $14$ chromosomes. How many pairs with different chromosomal composition can be prepared?

• A. $14$
• B. $2^{14}$
• C. $7$
• D. $2^7$

Answer 1

Answer: (D)

An organism can make $2^n$ different combinations of chromosomal compositions where "$n$" refers to number of homologous pairs; chromosomes are present in pairs and a diploid organism carries two complete sets of homologous chromosomes. Thus, $2n=14$ makes total $7$ pairs of homologous chromosomes which can form $2^7$ different combinations
