Hello There!

Mendel believed that during the formation of gametes, the pair of genes controlling a trait separate. He called this the principle of segregation.

Hope This Helps You!
Good Luck :)

The correct answer for the blank is -

Principle of segregation.

Explanation:

According to the Mendel's Principle of segregation, during the process of gamete (sex cells) formation, the gene variant (also called alleles) for each gene become separated from one another so that one allele is present in each gamete.

These pair of genes (alleles) control the traits (characteristics of the individual such as eye color, hair color, skin color etc).

Thus, priniciple of segregation is the right answer.

The sense organs that are located on the head and in the mouth of a fetal pig are the Ears, mouth, eyes, nose, and tongue. The pig, just like humans, experiences sound, sight, taste, smell, heat, cold, pain and also balance. The way it responds to these assists humans in the recognition of health and diseases. For instance pain and the posture will often indicate a specific disease such as a fracture of the vertebrae in the spine.
