Question

Nullisomy is represented by which chromosomal formula?

पर्याय

• 2n + 1

• 2n - 2

• 2n - 1

• 2n + 2

Answer 1

Nullisomy has the chromosomal complement of 2n - 2, which represents the loss of a single pair of homologous chromosomes. This is more severe than monosomy (2n - 1) where only one individual chromosome is lost.
