Explain How Phenotypes Are Driven By Dna Inheritance In Offspring

There are no two individuals that are completely alike, people vary by hair color, height, skin tone, gender and other endless possibilities. The reason for these variations can be traced back to our genetic make-up. A person as 23 pairs of chromosomes and each of these chromosomes carry one molecule of DNA. DNA itself is made up of adenine, thymine, guanine, and cytosine, then, these chemical compounds wrap around each other to form a double helix. These chromosomes contain around 20,500 genes and even with such a large number our variations are caused by less than 1% of our genes according to the Human Genomes Project in 2003. These variations also come from genotypes and phenotypes. A genotype is the complete set of genes that make a person’s hereditary, whereas, a phenotype are psychological, behavioral, and psychological features that result from the interaction between genes and the environment.

Environment can influence some personality traits, while others are genetic. The nature theory, heredity, determines such traits as eye and hair color, due to specific genes passed down from generation to generation. With the emergence of scientific studies of DNA, many scientists are finding more traits can also be associated with human cell encoding, such as intelligence, personality, aggression,

Traits get passed down from one generation to the next through Meiosis (cell division), where each parent gives you one Gene for each trait.

* How is it possible for an offspring to exhibit a recessive trait if neither parent exhibited that

Most phenotypes are influenced by both genotype and circumstances. Although, the genotype is a major influencing factor in the development of phenotype, the phenotype arises from the complex interactions between genes and environment.

Everyone has traits, but how do we get them? Your genotypes determine your phenotype (or trait). To determine your genotype, you use the alleles given from each parent. If an allele is dominant then it is expressed by a capital letter, and if it is a recessive allele then the letter is lowercase. Your genotype can be expressed in different ways, Homozygous Dominant (EE), Heterozygous (Ee), and Homozygous Dominant (ee).

Inherited traits are traits that are passed down form parent to offspring through genes. For example, in my paper pet family, one of the inherited traits is round eyes. This is because the offspring "inherited" the trait for round eyes from the parent. This is how inherited traits

“An organism's genotype is the collection of genetic variants it possesses. Its phenotype, by contrast, is its traits -- visible features of the organism like eye color, hair color, height and so on. Some traits can be affected by environmental factors” (Brennan). Cells copy their DNA when they divide and both daughter cells inherit an identical copy. Your genes carry the instructions for the growth and development of your body. However, your phenotype is influenced during embryonic development. For example, if you're malnourished as a child, your height at adulthood may be shorter than what you would predict based on your genes alone. Consequently, there can be more than one phenotype for the same genotype. Natural selection acts on phenotypes, so it only acts on the genotype indirectly. Phenotypes are driven by DNA because they represent the genetic makeup, the genotype. Phenotypes are the observable features of the genotype that is

The Human Traits Lab was meant to investigate certain traits that family, myself and peers exhibit. Phenotypes, such as widows peak, tongue roller, were to be determined and then compared with other peers. To begin to understand the lab an important concept must be explained first. Inheritance is defined as the passing of genes from parent to offspring. Each person inherits one allele from each parent to determine their genotype. The concept Mendel’s Principle of Inheritance includes four distinct inheritance patterns. The first is complete dominance, in which one allele beats the other. The dominant allele is represented by a capital letter while the recessive allele is represented by a lowercase letter. For example if the genotypes were TT

Varying from case to case, it is a fact that the complex exigency of relations between genotype and phenotype arise from the nature of an organism. Between any two random individuals there exists variation of ~ 3million nucleotide. The chemical structure of proteins; the relations between transcription and translation of proteins; the dependency of growth and physiology on both genotype of an organism and the progressive sequence of surroundings in which an organism develops and function and the randomized variations of molecular processes within cells. All these play role in mapping up what we are genotype and physiology

There are many genes within the human body, such as the dominant, recessive, and codominant genes. But, how is a gene classed as a recessive, dominant or codominant you may wonder. Well, the recessive allele only shows if an individual has two copies of the recessive allele. For example, the allele for having blue eyes is recessive as two copies of the allele are needed for a human to have blue eyes. A dominant allele always shows, even if the individual only has one copy of the dominant allele. For example, the allele for having brown eyes is dominant as only one copy of the allele is needed to have brown eyes and if you have two copies of the dominant allele you will still be given brown eyes.

As we have recently learned it was found that in most of nature’s occurrences, offspring inherits either trait from their parent in sexual reproduction. For example, when he cross breeded a white pea plant and a purple pea plant, the offspring had been either white or purple. However, there are exceptions to these findings. These five exceptions are known as Codominance, Incomplete Dominance, one affecting many traits, many genes affecting one trait, and the environmental surroundings. Codominance is the phenomenon in which two different dominant traits balance eachother out and in return, the offspring is a mix between both phenotypes which are equally shown. For example, with a genotype of XY for fur color. If X had represented white fur, and Y represented brown fur, then the offspring would

Each organism, cell or individual receives a pair of chromosomes from each one of the parents during development. Alleles are the genes found inside the chromosomes and consist of numerous variations such as eye color and hair color as well as many other variations. The alleles aid in the genetic makeup of a cell, organism or individual. The genetic makeup is referred to as genotype and may carry dominant or recessive genes as well as certain diseases. An individual’s limitations and hereditary character are determined by the genotype. A genotype is responsible for determining which traits are developed in an individual and play a huge role in developing an individual’s phenotype.

Well these genes are what change your hair color. As you get older your genes aren’t always going to be same as when you were younger. Also as you grow older your eumelanin genes become more dominant than you pheomelanin genes. This means that when you get older your hair will become darker or grey. Your hair also changes color during puberty. It changes color because you get more eumelanin genes as you mature more. So people with blond, red or a goldish color when they are younger are most likely going to have more changing in their hair color as they get older than a person with dark hair
