Vedclass · Answer

(A) Gynandromorphs in Drosophila are organisms that exhibit both male and female characteristics.They originate from a zygote that is initially female $(2A + XX)$.During the early cleavage stage (two-celled proembryo),one of the $X$ chromosomes fails to move to the daughter cell due to non-disjunction or chromosome loss.As a result,one daughter cell retains the normal female genotype $(2A + XX)$,while the other daughter cell receives only one $X$ chromosome $(2A + X)$,which develops into male tissue.Therefore,the correct chromosomal configuration is $2A + XX$ in one cell and $2A + X$ in the other.

Gynandromorphs develop in Drosophila when the two cells in the two-celled proembryo have one of the following chromosomal sets:
