Why is it impossible for male calico cats to exist

Biology
1 answer:
Kisachek [45]3 years ago
8 0

Answer:

genetics

Explanation:

calico cats must also inherit a gene unrelated to the X and Y chromosomes that codes for white fur. Because male cats have one X chromosome with code for black or orange and one Y chromosome with no color genes, they cannot technically be calico. About one in every 3,000 calico cats is born a male, and, unfortunately, don't live as long as female calicos due to their genetic abnormalities. XXY Syndrome renders male calicos sterile and can be the root cause of many other health problems

Blood flow
horrorfan [7]

Answer:

D. Tricuspid → right ventricle → pulmonary valve → pulmonary circulation

Explanation:

The circulatory system is the system of organs and blood vessels which is associated with the circulation of the blood in the body.

The circulatory system is divided into two portions: the systemic circulatory system (body) and the pulmonary circulatory system (lungs).

The vena cava brings the oxygen-poor blood from the body to the right atrium from where the blood is transferred to the same side of the ventricle controlled by the tricuspid valve (atrioventricular valve).

From the right ventricle, the blood is pumped to the pulmonary artery which transports the blood to the lungs where the oxygen will be exchanged.

Thus, Option-D is correct.
