Genectic Factors

. WHAT GENETIC FACTORS ARE INHERITED BY HUMANS?

* Human genetics is the study of inheritance as it occurs in human beings. Human genetics encompasses a variety of overlappingfields including: classical genetics, cytogenetics, molecular genetics, biochemical genetics, genomics, population genetics, developmental genetics, clinical genetics, and geneticcounseling. Genes can be the common factor of the qualities of most human-inherited traits. Study of human genetics can be useful as it can answer questions about human nature,understand the diseases and development of effective disease treatment, and understand genetics of human life.

* For example, for the gene that determines eye color, theremay be an allele for blue eyes and an allele for brown eyes.
You may inherit a brown allele from your mother and a blue allele from your father. In this instance, you will end upwith brown eyes because brown is the dominant allele. The different forms of genes are caused by changes in the DNA code.
The same is true for medical conditions. There may be afaulty version of a gene that results in a medical condition, and a normal version that may not cause health problems.
Whether your child ends up with a medical condition willdepend on factors including:
* what genes they inherit
* whether the gene for that condition is dominant or recessive
their environment, including any treatment they mayreceive

* By answering such cuestions, Each cell in the body contains 23 pairs of chromosomes. One chromosome from each pair is inherited from your mother and one isinherited from your father.
The chromosomes contain the genes you inherit from your parents. There may be different forms of the same gene. These different forms are called alleles.
