The chromosome number of the four resulting gametes with respect to the normal haploid number shows <u>n + 1; n + 1; n - 1; n - 1</u> <u>(option A)</u>.
During aligning of all the homologous chromosomes, in the process of meiosis, new cells are formed.
From the total number of chromosomes one chromosome is missing , the resulting chromosomes are +1 and -1. Similarly for the second cell, resulting chromosomes would be +1 and -1.
This makes four gametes i.e. -1 and -1 and +1 and +1 respectively.
