Question

Which one has the copulatory organ?
A)Squirrel
B)Snake
C)Toad
D)Parrot

Answer 1

Hint: The male animal uses a copulatory organ for insemination, that is, directly into the female reproductive tract to deposit spermatozoa. Among vertebrates, there are various types of copulatory organs.

Complete answer:
Highly specialised and diverse genital structures have evolved for animals with internal fertilisation to transfer sperm into the body of the females. These copulatory organs come from various parts of the body, some of which are ancestral to the reproductive system, such as the penis, and others are derived from fins, arms, legs, or other appendages of the body. Using muscles, hydraulics or both, they are obliterated or unfolded. Nerve supply is known to be an intrinsic property of copulatory organs .

Squirrels have a pseudo-penis-like structure which is small in size and is a copulatory organ.

There are a pair of sex organs called hemipenis in male snakes and these expand and discharge the sperm into the female snake. As with each examination, the two reproductive organs of a male snake work.

The majority of birds do not have the same portions of the reproductive body as humans. Both male and female birds have a cloaca instead. For their digestive, urinary, and reproductive systems, this opening (also called the vent) acts as the body's escape.

Hence, the correct answer is option (A)

Note: Size is one characteristic of copulatory organs that are subject to certain selective pressures. Longer organ benefits can include greater courtship signal efficacy and longer 'distance' when trying to copulate with evasive females. Longer organ costs may include reduced locomotion, higher energy costs, or decreased mechanical compatibility with female genitals. With mating activity, the optimal size for a copulatory organ can differ.
