How genetic components provide our basic genetic endowment

At this moment, half of these pair of chromosomes comes from the father and half from the mother to form the offspring genetic makeup. However, the 23rd of these chromosomes determines the sex of the child. The mechanisms by which gene transmit information Genes determine the sex of a child. However, the basic genetics in the human life include the dominant trait, recessive trait, genotype, and the phenotype. Genes are transformed to the child depending on the genetic nature of the parents. Parental testing is done in three different forms. Ultrasound sonography is screening done in the first trimester to test the overall development of the baby, the risk of genetic conditions, heart defects or cystic fibrosis. However, chronic villus sampling is a screening done in the first trimester and involves taking a tissue of the placenta also to test genetic abnormalities such as Down’s syndrome.

On the other hand, amniocentesis is a procedure done on the second trimester and used to get the amniotic fluid sample from the amniotic sac to diagnose the presence of any genetic disorders and open neural tube defect depending on family history. How environment and genetics work to determine human characteristics Individual’s level of temperament is an arousal and emotionality pattern representing an individual’s consistent and lasting characteristic. Further, some personality traits such as neuroticism have a linkage to genetic stability. Moreover, the environment plays a part in individual’s personality. In addition, genetic components development of disorders such as schizophrenia whereas the external factors determines if the individual will display the trait or not. Thus, children may influence their environment through genetic traits.
