Answer:
Of the 23 pairs of chromosomes in any normal human cell, the first 22 pairs provide directions for an individual's body and brain development. Scientists now estimate that about half of a person's personality traits and cognitive abilities can be traced to genetic influence and that psychological disorders arise from the interactions of many genes.
Explanation:
Chromosomes are small molecules that have the ability to carry all the genetic information needed to form a living being. These chromosomes are donated by an individual's parents and are used to form 23 pairs that determine all the internal and external characteristics of an organism. Among these 23 pairs, one pair will be responsible for determining the individual's gender, and the other 22 pairs will be responsible for the instructions that will make up the entire body and brain of the individual. Many scientists believe that chromosomes are responsible for even a part of a person's personality traits and that the genes they carry are directly related to the existence of psychological disorders.
The correct fillers for the given statements are: "22" and "personality and cognitive abilities"
Chromosomes are thread-like minute structures found in the nucleus of the plant and animal cells. These are the structures that help in transferring genetic information from one generation to another. Half chromosomes come from the mother and half come from the father's reproductive cells.
- Humans have 23 chromosome pairs in their cells, one out of 23 pairs is responsible for the gender of the human embryo or child.
- the other initial 22 pairs are responsible for providing directions for an individual's body and brain development.
- On the basis of studies, many scientists say that almost half of the traits of personality and cognitive activities or mental processes to learn or acquire activities are due to chromosomes.
Thus, the correct answers are : "22" and "personality and cognitive abilities"
