"For the majority of conditions, what you've inherited is a susceptibility to a disease or condition," Dr Barlow-Stewart says. "To happen they need a triggering factor and, although we don't know what all these factors are, there are some like smoking and poor diet that we do

Much of how an individual turns out to be is not only dependant on the genes in which their parents have passed down to them, but also due to the family structure in which they were raised by.

People with a family history of a disease are more likely to get it. But, this is not always the case. Some people without any history of disorder in their family can still be at risk as well. Family history gives an idea if a person is more likely to get common disorders, including: heart disease, high blood pressure, strokes, cancers, and diabetes. Less common mutations on a single gene, like cystic fibrosis, can also be evaluated given a person’s family history (Inheriting Genetic Conditions 1). If natural selection is taken out of the equation for people that have diseases, then these genetic abnormalities get passed on. “Survival of the fittest” has always been the motto for Mother Nature. When medicine can cure or sustain a younger sick people’s lives for longer than biologically natural, they have an opportunity to reproduce. Reproduction for people with genetic diseases has possible negative consequences. The diseased individual passes on their mutated genetics to their offspring, who in turn pass it on to their offspring, and so on. Now, more humans have genetic problems than in the past. Down syndrome is a

that gene supplied or not. If there is no dominant gene showing up, then they will show through

Not all heritable traits are going to be given to the offspring. Inheritable traits are traits later learned in life. Genetic tools such as Punnett squares, and pedigrees can help us determine the heritable genes. Some genes can skip an offspring and go to the next. It's normal to have different features from your parents but the same as your grandparents. Genetics are very important to learn and to know about.

Genetic inheritance is a study field that presents twists and turns. Time reveals new discoveries about how other factors affects inheritance. The new discoveries will offer clarity to the issues of heredity and why certain people are different, yet they have identical genes. The documentary “Ghost in Your Genes “ expound on the subject of varying inheritance patterns.

This paper will discuss how phenotypes are driven by DNA inheritance in offspring by the genes known as alleles. Each parent provides an allele although on allele is hidden in one parent and can be passed on to his or her offspring. The information presented in the monohybrid cross that shows where one parent has the hidden allele of a gene that carries the trait of orange eyes that disappears and reemerges later in the genetic make-up of an offspring. The inheritance in the offspring is driven by the DNA of that individuals parents and the genetic traits one is born with are decided by the dominant and recessive genes of his or her parents (www.nature.com, 2014).

A chromosome is made up of genes, which is sort sections of DNA (Deoxynucleic acid) . Within the genes, there are alleles, which are different forms of a gene. For example the gene for eye colour has an allele for blue eyes and an allele for green eyes. Alleles can be either dominant or recessive. The characteristic controlled by a dominant allele develops if the allele exists

Actually, there are some significant consequences to it and one of the ones that he brings up that I point out to them is that the eye color. Everyone thinks brown eyes, blue eyes or brown eyes dominate to blue eyes and that is the way that we always teach it. If you have two blue-eyed parents you shouldn’t have a brown eyed child and if you do then somebody did something wrong. The clue, who’s my daddy come up.

The shaded squares are the recessive alleles however the non-shaded squares are dominant alleles. Recessive alleles only occur when the phenotype is homozygous recessive. For a recessive allele to produce, it is required to inherit copies of recessive genes from both parents, but even if both parents are carriers, only one out of four of the offsprings are likely to be affected. Furthermore, recessive alleles normally appear out of nowhere and skip generations, conversely, dominant alleles rarely skip generations, which makes them easy to follow through a pedigree.

This table helps show all the possible genotypes from one set of parents. The table shows that the genotypes purple and starchy are dominant, and the genotypes yellow and sweet are recessive.(stallsmith)

The pairs of alternative traits examined segregated among the progeny of a particular cross, some individuals exhibiting one traits, some the other

Genes build the phenotype of humans as well as the underlying genotype. Competition between cultural genes leads to varied success of genetic determinism. It can therefore be said that learnt traits such as those espoused within a specific culture, can produce what may seem to be the genetic genotype of an individual. Genes are not always advantageous in the

There has been a lot of scientific research done into genetics, genetic crosses and inheritance enabling us to understand why we have the certain characteristics and traits that we do, how we inherited them and how we can pass them on. It’s because of this research that we can understand and learn about our genetic makeup and why it effects the way we are.
