Hint: Loss of X chromosome in particular cells in early development may cause certain genetic disorders in an organism which may result in the appearance of both male and female characteristics in the individual.

Complete answer:
As a result of the loss of the X- chromosome in particular cells during its development, the individual gains both male and female characteristics, and the organism is known as Gynandromorph. Some notable Gynandromorph organisms are butterflies, moths, and other insects. An example of such an organism is the Zebra Finch birds which possess a lateralized brain structure in the face of a common steroid signal that provides strong evidence of a non-hormonal primary sex mechanism regulating differentiation of the brain.

Additional Information: Meta female is a fruit fly with a phenotype of females in which the ratio of the X chromosome to autosomes is greater than 1.0. For example, if a fly possesses three X chromosomes and two sets of autosomes, it will be considered as a meta female.
Triploid individual shows a chromosomal disease known as Triploidy in which the fetus contains three copies of every chromosome. Most of the embryos with such disorders end up with triploidy miscarry early in development.
Myotonic dystrophy is another long term genetic disorder which causes dysfunctioning of muscles and shows symptoms like gradual worsening muscle loss and weakness, cataract, intellectual disability, and heart conduction problems.
So, the correct answer is “Gynandromorphs”.

Note: Gynandromorphism was first observed in Drosophila by Bridges and Morgan and later was seen in many other animal species including crustacean and birds. The cause of this disorder is the loss of an X chromosome during mitosis in a cell. Currently, it is used as a powerful tool in genetic, development, and behavioral analysis in the study of several species.
