20 babies were born in the ward, 10 of them had blue eyes and the other 10 had brown eyes.
% of blue eyes babies is 50% and % of brown eyes babies is also 50% (10/20*100).
<h3>What is a Dominant trait? </h3>
Brown eye color gene is a dominant trait, and it can express itself in pure breed condition as well as impure breed condition.
Blue eye color gene is recessive and can only express itself in pure breed recessive condition, the dominant gene repress the expression of the recessive gene phenotypically, but the genetic makeup remains the same.
Hence, the blue-eyed babies have pure breed recessive genotype and brown eyed babies have pure breed dominant genotype or genotype.

Answer:
Thalamus, hypothalamus, and epithalamus
Explanation:
Diencephalon, the central core of the brain is located superior to the midbrain. The thalamus, hypothalamus, and epithalamus together make diencephalon.
-Thalamus makes around 80% of the diencephalon. Thalamus consists of two nuclei of gray matter along with interspersed tract of white matter.
-Hypothalamus is the part of diencephalon that is present inferior of the thalamus.
-The pineal gland and habenular nuclei together make epithalamus that is located posterior to the thalamus.
Answer:
The correct answer is option c.
Explanation:
Starting from the initial primates to the hominids, and eventually, to Homo sapiens, the brain of humans has grown spontaneously. The volume of the brain has increased with the evolution of humans, that is, starting from about 600 cubic centimeters in Homo habilis to 1600 cubic centimeters in Homo neanderthalensis. The Homo neanderthalensis was the hominid with the largest size of the brain, that is, with the maximum cranial capacity. The enhancement in the size of the brain ceased with neanderthals. After that the shrinking of the brain size took place.
