Viviparous germination is a type of seed germination in which seeds germinates but still attached with the plant body. This type of germination is present in plants such as Sonneratia and Rhizophora. In these plants, the embryo which is present inside the seed grows and break the seed coat and after that, it comes out the fruit which is still attached to the plant.

Answer:
Pleiotropy
Explanation:
Marfan syndrome has several signs and symptoms depending on the individual affected.
The main manifestations of the disease are related to the skeletal system, in which the affected individual presents with elongated limbs, elevated height, scoliosis and thoracic deformations; the cardiac system, characterized by mitral valve prolapse (closing of the upper and lower chambers of the left side of the heart) and dilation of the aorta; and the ocular system, characterized by a detachment in the lens of the eye, and myopia.
The ability of genetic defects such as Marfan syndrome to reach such distinct organs is called pleiotropy.
Urbach-Wiethe disease is a rare genetic disorder that can cause calcification of brain tissue in the temporal lobes; this calcification can cause damage to the amygdalae.
<h3>What are the symptoms of Urbach-Wiethe disease?</h3>
The symptoms of the disease vary greatly from individual to individual.
They may include a hoarse voice, lesions and scarring on the skin, easily damaged skin with poor wound healing, dry, wrinkly skin, and beading of the papules around the eyelids.
<h3>What part of the brain does Urbach-Wiethe disease affect?</h3>
(1994, 1995) investigated a patient suffering from Urbach–Wiethe (UW) syndrome, a very rare autosomal recessive disease, which produces bilateral calcifications in the anterior medial temporal lobes, especially of the amygdalae, in 50–75% of cases (Newton et al., 1971; Staut and Naidich, 1998).
