Answer:
- A gene is a stretch of DNA that helps to control the development and function of all organs and working systems in the body.
- Genes are passed from parent to offspring; the combination of these genes affects all aspects of the human body, from eye and hair color to how well the liver can process toxins.
- A human will inherit 23 chromosomes from its mother and 23 from its father; together, these form 23 pairs of chromosomes that direct the inherited characteristics of the individual.
- If the two copies of a gene inherited from each parent are the same, that individual is said to be homozygous for the gene; if the two copies inherited from each parent are different, that individual is said to be heterozygous for the gene.
- gene: a unit of heredity; the functional units of chromosomes that determine specific characteristics by coding for specific protein
- chromosome: a structure in the cell nucleus that contains DNA, histone protein, and other structural proteins
- genetics: the branch of biology that deals with the transmission and variation of inherited characteristics, in particular chromosomes and DNA
