Answer:
The major differentiating factor between heredity and inheritance is the way the genetic traits are interpreted. Heredity is the transmission of genetic characteristics from parents to offspring and is often referred to as genetics.
Answer:
What are the main differences between the terms hereditary and genetic?
The subjects of genetics and heredity are inseparable from each other, but there are so many details that it is extremely difficult to wrap one's mind around the entire concept.
For example, a child of parents none of whom had any defects in their genes may inherit 47 chromosomes instead of the usual 46 and therefore will be diagnosed with Down’s Syndrome. That would be quite surprising for either parent. While the study of heritage from family records couldn’t have predicted this outcome, it is the study of genetics that clarifies what has happened to the child.
Another instance of unpredictability in heritage is the recessive genes. Both parents might have possessed the same type of recessive genes in their genitive make up for several generations but their heritage might have not revealed because one set of recessive gene alone cannot express itself in the offspring. When the two sets of recessive genes are combined, it gets expression. For example, a set of parents might have had brown eyes and either of whom might not have known that they possessed recessive genes for blue eyes in their heritage. Now for the first time when they join together, the recessive gene for blue eyes might be given expression.
These are the subtle ways study of heritage differs from study of genetics.
