Question

Gyanandromorphs are animals having:
(A) Same sex in all cells of the body.
(B) Different sexes in all cells of the body.
(C) Same sex in different cells of the body.
(D) Different sexes in different cells of the body.

Answer 1

Hint: These are the animals that exhibit traits common to both male and female humans. Gynandromorph is a name frequently used in entomology to describe these, which are primarily seen in insects.

Complete Step by Step Answer:
The latest instance of the bilateral gynandromorph in nature was in 2019. This bird can reproduce, which is unusual for gynandromorphs, thus there might be more than one in the vicinity. Spiders, ticks, flies, locusts, crickets, dragonflies, ants, termites, bees, lizards, snakes, rodents, and numerous kinds of birds have also been found to exhibit it. The zebra finch is a noteworthy example of a bird. Bowen and Hanson provided an explanation for A's initial flawless gynandromorphism. salina, resulting from chromosomal loss in one of the two daughter cells during a heterogametic (female) zygote's initial cleavage.

Gynandromorphs are people whose bodies have female characteristics in some areas and male characteristics in others. They occur when a cell loses one X chromosome during the first mitotic division. Half of the offspring will be female and half will be male in the various cells of the same body in the 50% resulting progeny. When sperm fertilize both the egg and the polar body, a gynandromorph may result because the two zygotes may interact and swap cell combinations. Infections from bacteria and viruses, temperature changes, and mutations have all been linked to the emergence of gynandromorphs.

So, option (D) is correct.


Note: The biological definition of an intersex is a genetically homogenous individual, in contrast to a gynandromorph, which is equivalent with a sexual mosaic. Arthropods and birds have gynandromorphs, but humans and other higher organisms, where sex is determined in more complicated ways, do not.
